The showdown begins as soon as action on the river is completed. My assumption has been that the OP's scenario took place during the showdown (although I pointed out that his description is somewhat vague and could be read ambiguously).Because there is no showdown yet, thus you are flirting with one player to a hand. How would you feel if you showed down your cards and the guy was about to muck and the guy next to him said "just turn your cards over", and it cost you to lose the pot?
It is each player's responsibility to play their hand until showdown. Once hands are shown down, then it is everyone's responsibility to make sure correct winning hand gets the pot.

Saying "You should show your hand" is very different from "The hand he just tabled is Queen high". The first is instruction on how to play (arguably, although that's a deeper and more fundamental question worth getting into another time), the second is stating a fact about the current state of the game, comparable to saying who the action is on or what the current bet is. Stating these sorts of facts doesn't make up a OPTAH violation.
