That isn't the (horribly sidetracked now) point under discussion though. The updated stealth rules are rules for a combat situation. I.e. If a enemy dives behind a overturned table out of LoS in battle it has to make a stealth check or you know its exact location, yes. That is why at the start of the errata it says a stealth check is made at the end of a *move action*. Move actions don't exist in the same sense out of combat.
To illustrate the point as plainly as possible, you can be following a orc outside in the distance 500 yards away and if he disappears into a thick forest, he does not have to make a stealth check in order for you to stop knowing his exact square. This is a role-playing situation and he simply disappears into the forest. Any DM that would continue to tell the players the orc's exact location until the orc made a steatlh check, all the while while he wanders a mile into the woods, and the party is 500 yards back on the plains... would be off their rocker.
