I would say reasoning for waiting is to get your aim. If you shoot first and miss you likely aren't going to get a chance to shoot back because negotiation/begging/mindgames are over. Other reasons are probably just the thrill of having power over someone's life, letting them take in that they messed with the wrong guy.
This is good logic, but for the most part, the whole 'Mexican Standoff' is just a Hollywood cliche - more common on television than in movies.
If you're a bad guy and a cop points a gun at you and tells you to freeze, he's doing so because he is trained not to shoot people impulsively and to give you every opportunity to surrender peacefully. He also understands that if he hesitates too long, it can cost him his life. If you stop running, you have three choices:
1) Pull a gun on a guy who's probably a better shot than you and has already taken aim at you, and take your chances that you can hit him first without aiming at all.
2) Pull a gun on a guy who's already aiming at you and hope you can point it at him before he kills you dead. Then maybe you can stare him down and intimidate him into dropping his gun so you can double-cross him and shoot him.
3) Surrender.
Most people stupid enough to draw on an armed officer get dead. When an armed cop gets shot its usually because he was outnumbered or just didn't see it coming.
