so if cam and crank marks are both lined up, only the IP can be out of sync.

OK, I agree.
I view it as both the crankshaft and the IP being out of phase with the camshaft. I do not believe that it's possible to lose the timing between the IP and the crankshaft under normal circumstances.
So, a possible scenario is the IP out by 180 degrees with respect to the camshaft..........but, I don't see how this can occur unless the camshaft is removed from the vehicle during the process.
