That does make a whole lot of sense. The taxiway name change may have crossed the pilot up. Although I'd still be surprised that he'd miss the big white "26" on the sign at the hold short point...assuming that it's visible in the dark. Not all airports light their taxiway signs, and the taxi/landing lights on the CRJ may not have let him see it maybe?

At the very least I think that both pilots would have checked their heading.
