Narrative:

While exiting runway 25L; we understood that we were cleared to cross 25R while we were going through the usual after landing calls/callouts. The first officer repeated the clearance to cross the right runway and no communication to the contrary was received. We had no knowledge of an incident until today. It is difficult to understand ATC instructions sometimes as we are in the middle of reverse thrust; braking; steering; and making callouts; etc. I distinctly recall the repeat of the clearance to cross for our flight by the first officer. We checked both ways and crossed.
