Because the differential thrust is not being used to decrab the airplane - the rudder is still doing that. The thrust is being used to create additional sideslip normally supplied by wing drop, which IS limiting because of pod strike considerations.

Agree. But when the rules of man comes against the laws of physics, who wins?
My FCOMS tell me not to dick around with differential reverse on rollout either. But if the **** hits the fan and we start sliding towards the edge, I know which lever I need to pull to get us back on centerline.
