Narrative:

Having landed on runway 30 at mia, we were cleared to taxi to the ramp via taxiway Q. We were following a B757 on taxiway Q, and asked ground for clearance to transition to taxiway P via taxiway south. We were then paralleling other B757 who was still on taxiway 1. As we entered the ramp area near our gate, the go noticed that the other B757 was now converging from the right due to the way taxiway Q turned in toward the ramp area. The first officer notified the captain of the proximity of the aircraft, and he turned left off the taxi centerline. The other B757 aircraft came to a stop and advised ground of our convergence. At no time did we feel there was danger of colliding with the other aircraft, and indeed, the tower supervisor subsequently confirmed by telephone that adequate spacing existed via their ASR.
