Narrative:

Seatac airport has 2 parallel runways, runway 16L and runway 17R. After landing, we cleared runway 16R at intersection M between the runways. Tower cleared us to cross runway 16L and enter the taxiway behind a B737 which was taxiing northbound. My first officer read back the clearance. I was looking down runway 16L making sure it was clear and did not hear the part about passing behind the B737. I taxied in front of the B737 and they had to stop. It was my fault in not catching that last part of the taxi clearance and being in a little of a rush to clear runway 16L. A contributing factor also was a failure of crew coordination. The first officer might have prevented the situation by informing me to pass behind the B737 and not in front of it. Afterward, we did have a discussion about the event and [the need to] coordinate more closely on all clrncs. I now verify all taxi clrncs with the first officer so there is no misunderstanding on my part.
