This idea was extended in the ekpyrotic model, which allows the branes to move and collide, explaining the big bang and providing a string theory alternative to in ation. The ekpyrotic scenario does not say the big bang never happened, rather it explains the big bang without evoking a singularity. Once the brane collision has occurred, the universe evolves according to standard bigbang theory on the branes.
