The ball bearings have lubricant that can shift over time due to gravity. And the metal parts might weld to each other over time if they are not moved.

How likely are these things to actually happen?

I think the welding takes more than a year. The lubricant settling probably depends on the quality of the drive and the ambient temperature. And I guess the ball bearings would be pretty tolerant (since you only have to move them a little to get the lubricant on them again), it's more likely that the heads would stick.
