I agree the formal strategy-stealing argument relies on literal symmetry; I would say the linked post is applying it to asymmetric situations, where you can recover something roughly symmetric, by assuming that both players need to first accumulate resources and power. (I think this is basically what you said.)
Yes, all of that mostly sounds right to me.
