With the car in gear and the clutch pedal up, the clutch disc is in contact with the flywheel which spins the input shaft of the trans, the drive shaft then the wheels. The tip of the input shaft sits in the pilot bushing. The input shaft has splines which goes through and aligns with the clutch disc.

The throw out bearing makes contact with the diaphragm. It goes over the input shaft. When you push the clutch in, the CSC pushes on the diaphragm to disengage the clutch disc.

Are we not getting all the deets? Or am I just not thinking enough of how this could have happened?

Yes coincidences happen. I've fixed cars for what it came in for and as the lot attendant goes to take the car to the drive, the check engine light comes on for something else and I'm labeled as a thief.
Highly possible that this was the final drop to a hurt pressure plate.

The most likely theory if it's not the previous one is that the clutch offered enough grab. You have to understand that the transmission was not giving in locking the entire drive train. You'd expect the clutch to give up however if the disc does catch and grab the drive train starts to put pressure forward since the wheels are trying to spin. This puts upwards and downwards pressures on the input and output shaft as well.

The more I keep explaining it starts to sound like this would really only happen on a hurt pressure plate, though possible that it has the ability to mess up a plate, if it's hurt (worn teeth) it will bend them
