Saving time by laying casing during spawn run...? Eh?

This will certainly sound goofy to many, but for some reason I've found the idea of casing confusing. From what I know, its for:
- retaining water
rehydrating the surface of the substrate making a somewhat protective barrier from contams (non-nutritive) providing an easily penetrable layer that allows gas exchange and easy primordia/fruit penetration
It's possible I overlooked or didn't know about ofther functions of casings. Anyways, what would be the disadvantage to laying the casing layer down immediately after laying the substrate? Then, couldn't you just wait until the substrate is fully colonized, and then encourage pinning? There have to be ways of knowing when that time is (ie. transparent sides of grow tray, that could be covered). Anyways, provided we could tell the right time to encourage pinning, would there be any disadvantage to this technique of casing while laying substrate/spawn?
Thanks for reading this ridiculously long post

The 'old' way was exactly that. The substrate would be spawned, and the casing laid on top. It still works to do it that way. What we've found however, is that pinsets and eventual yield can be increased by letting the substrate fully colonize in a high CO2 environment, and then let the casing layer colonize partially in a high CO2 environment, and then at the precise time, expose to fresh air, light, etc., all at once to trigger very nice flushes.

Right.... but I don't see how that any different? Unless your saying by laying both the sub and the case at the same time, the case will be overly colonized (or at least over the ideal level of colonization) at the time the substrate reaches full colonization..
I think that's what your saying right? Also, does a nutritive casing layer have any additional drawbacks outside of being a nice home for contaminates? Thanks bud, your a star.
Oh, and one more thing.. this sounds dumb but I just want to double check. The mycelium is using oxygen during its colonization, right? How exactly does an elevated CO2 level during colonization help? I've heard this elsewhere, too, but I don't get it. Isn't it a byproduct?

Imagine in nature. Mycelium will spread under ground (high CO2 environment as it is using up what little oxigen there is inside a pile of fermented/ing matter). Then it gets to the surface and is exposed to fresh air and lots of oxigen and it realizes it is pinning time.
A nutritive casing layer defeats the purpose of casing as it will be colonized by the mycelium. Imagine casing as a sponge. It will suck up lots of water and feed it slowly to the substrate, while at the same time providing a humid microclimate. If your casing colonizes there will be less spaces between the bits of casing material for water and air to be "stored".
Also, a colonized casing layer is prone to overlay, which hinders pinning a lot.

You might find this link useful.
Some people (fahtster among them) are playing with the idea of "late casing". In this case you allow your bulk substrate to start pinning and once it does you add your casing mix. THis way it doesn't colonize at all.
