I think its an ease of use issue, if you clip it in place.....its "stuck" there clipped to the grate.....then at some point it gets lost...that being said...
I've used potato, apple, a bulb of garlic....just somethin to keep it off the grate, well keep it from falling thru the grate...
My reasoning is MY pit is a "semi" offset so my temps are different across my grate so every one in a while I like to move the temp probe around to see my hot and cold spots...to help me become a better coook
Til next time, chew carefully, and dont let your meat loaf!
