IMO no on over extending as you say ,,, The screw that holds the piston is a 2-56 very fine thread , it's not pulling out of the shock shaft its backing out due to vibration un threading it self if you will ,, if the piston spins freely then it wont grab the screw and back it out ..

A bad engine bearing that buzz's when you rev it up will cause this as well ,,
just for kicks try this put a un-lock nut and a washer on say the top shock mount ,leave it loose ,start up your engine and watch what happens to the nut when you rev up to 30k rpms.
