My understanding of it is this (but I could be wrong):
Any stripped lower can be registered as either a pistol or rifle. Pistol lowers are normally marked as such.
If you register it as a pistol, you can make a rifle out of it too......as long as the barrel is at least 16".
If you register it as a rifle, you can never make it into a pistol.
If you have multiple AR's, always keep the pistol upper attached to its lower and never swap around. If you do so without thinking a lot about it, you could end up carrying around an unregistered SBR.
