Update:
Co-pilot flying. Pilot experienced but not necessarily on the 757. A miracle no other planes were taxying at the time not to mention the fact there were no service vehicles out there either.
Crew reportedly realized their mistake after landing and communicated that fact to ATC.
Glad to see nobody got hurt. Mistakes happen. Thr only people who don't make them are people who don't do very much in the first place.
