Catch or No Catch?

[Jerry]

In all due respect to my peers. Why would this be any different than a fielder making a catch, running towards the dugout at the end of the inning, tripping enroute and dropping the ball?

Time of possession has to be taken into consideration. Once the out is made, that being the fielder have secure possesion of the ball, there's no reason to even suggest he needs to remove the ball from the glove. Am I missing something here?
