It is not. I'm not sure to what this is in reference.
If we have reverted to talking about win goals, the reason I find the decision peculiar is that if you set a "win goal" and reach it you should never play again...ever. You set a goal, you reach that goal, you are done.
I see no (logical) reason why you should get to wipe the slate clean, reset the clock and disavow your decision from the previous day.
I'm in full support of leaving due to fatigue, hunger, time constraints, etc... I cannot for the life of me see why a win (without these other factors present) would signal a time to leave, when you will be returning to the same conditions you left. That's all, it doesn't make sense to me.
We just debated this on LVA and the conclusion was there was no logical reason to leave as a result of a win. We found many emotional factors that could account for it and I don't think anyone is saying that there is anything wrong with including emotions in your casino decisions.

P.S. Of course, I would have been fired from the team for including emotions in any casino related decision.
