maybe he shouldn't have, maybe a safety was supposed to be back there too, maybe not. Either way, it was still good coverage and if he had taken away the inside and he goes to the outside, a pass over the outside shoulder on pinpoint target is still a completed pass. Maybe it's a more difficult throw, but it it's as on target as the other one, it's still a TD. There was an open point of the field to throw to no matter where he went and a perfect pass is hard to defend. Regardless of if he let him have the inside position to easily, he was still in a good defensive coverage overall. Like I said, I'd take that type of coverage from every guy on the field and we'd have a dominating pass defense because it's going to result in incompletions, defenses, or INTs more often than a perfect pass completed.
