The gears work the same either way.
Now, it may be that Continental did a crappy job designing the anti-thrust bearings in the engine, and that bearing surface just can't handle load very well. Or it could be that the power pulses from the engine cause the gears to switch between one loading direction and another (this actually makes the most sense).
The GTSIO 520 is known as a rather temperamental engine and I think a lot of the things that people do to "be nice to the engines" are really just rituals that have no scientific basis. But hey, what do I know...
