Air, like most things, doesn't like to go around bends. Air flow will be higher at the "outside" of the bend. With the split of the pipes before the throttle bodies, I suspect more air will flow through the pipe closest to the firewall as the airflow doesn't have to "turn" as much.

This is an exaggerated illustration, with an abrupt 90 deg bend but it shows the general idea.
