upside down cakes?

I noticed that was seeing more growth from the bottom of some cakes, so I flipped them. A friend saw me and we started to argue about whether this was good or not. He started saying that he read here it was important to maintain the same side up after birthing, so i started searching to get a good answer and I've found people going both ways.
I think this is what my friend was talking about

Birthing the Cakes
Once a cake is completely covered in white mycelium, wait at least 1-2 more weeks before taking the cake out of the jar. When you are ready, and in a fairly clean room, begin transferring the cakes from their jars into their fruiting chamber (described in the next step). Remove the lid of each jar, and dump out the dry vermiculite on top. Then, remove the aluminum foil seal and put the lid back over the top of the jar. Slowly turn the jar upside down, so that the cake is resting on the jar lid. You may need to gently tap the jar to knock the cake loose. Take the jar off the top of the cake and then carefully pick up the cake and turn it over, so it is sitting right side up on the lid. It is very important that the cake is fruited in the same orientation (with the same side up) as it had when it was incubating. If it is turned over during birthing, it will try to fruit from the original "top" side of the cake, even if this side is now facing down. This is bad, because the mushrooms can?t grow correctly from the underside of the cake, and you will grow very few mushrooms. Leaving the cake sitting on the jar lid, put them both into the fruiting chamber. Once all the cakes have been transferred, you?re ready to induce fruiting.
Seems pretty clear to me. *shrug* I plan on keeping them verm-side up...that's how they're sitting in the incubator.

but yea idk, whats the general consensus, because this was years ago and in my own current experience things are looking ok

Never had a problem with flipping cakes. It's all good don't worry.

It's been long known that flipping a substrate from its original position during colonization is a major pinning trigger. Shiitake growers have used this technique for centuries.
In addition, the bottom of 1/2 pint jars is convex, leaving a concave indentation on the bottom of the cake. After birthing, if this side is placed up, it gives a place to pile up some vermiculite which can then be soaked with water every few days.
Once a cake is pinning, leave it the hell alone. However, after birthing, flipping the cake so the original bottom becomes the top is desired. It's not absolutely necessary of course, but desired. It's also not necessary to baby cakes during birthing. If it doesn't seem to want to come out of the jar, slam the jar down on a cutting board or some other wood surface hard enough to dislodge it.

Is this primarily because of the slightly concave bottom? Are there other reasons for this?

I've definitely found this to be true, especially with WBS, but do you know the actual reasoning behind why this works? I understand it's a pinning trigger but I'm just curious as to why it is.

yea is there is something specific about the composition of the cake that encourages this? also i meant flipping them over in the FC, i dont know if that makes much difference in this conversation But this whole concept had me thinking all day, if i were to take any plant, and set it up upside down, so the soil pot was hanging in the air, water went in the bottom (now top) , and i put lights on the floor shining up, would it affect growth?
but im just interested in food for thought, i know a human being wouldnt last long before passing out if hung upside down, and obviously we are slightly different then myc
either way thanks for the information
