Narrative:

We were holding behind a B737, short of runway 23R in MMMX on taxiway B6 after landing on runway 23L. The tower said something in spanish, and the B737 started to move onto runway 23R. The tower then told us to follow what we heard him to say, 'air carrier X' down runway 23R and exit at B5 to taxiway B. We assumed air carrier Y had just landed on runway 23R, but didn't see an air carrier X aircraft anywhere. So, we asked the tower the location of the air carrier X, we were instructed to follow. He then said to follow the aircraft ahead on runway 23R, which was an air carrier Z, B737. As there were 2 air carrier Z, A320's on taxiway B either side of taxiway B5, it looked like I couldn't exit runway 23R there, and the B737 we were instructed to follow had already past taxiway B5 and was exiting on B3. I continued to taxi on runway 23R past B5 to exit at B3 onto taxiway B. Tower then asked us why we passed taxiway B5, and it was only then that I realized that he didn't want us to follow the B737 to B3. Supplemental information from acn 617508: once parked, an air carrier representative told us we had to go to the airport auths. We did, accompanied by the station manager, filled out a report for the incident.
