As a side note, you can't technically cut post actions at all unless, A, the person used an 'If' statement.B, the action is literally impossible to complete due to preconceived assumptions no longer being true, which is kind of like a If statement in itself.

If that's true, then Vordak wouldn't be able to change anything in his previous post that would have happened before my feet hit his chest. 

So we've got two schools of thought on the issue. One that says anything in the previous post can be altered, and one that says it can only be altered if it was written with an "if" statement or you're interrupted by your opponent. Anybody got a link to somewhere that would tell us which is more commonly accepted?
