Very good point. At 0:25 the camer (quickly) pans the right wing and up to the evacuation at L1. Ar 0:40 it pans from the tail of the aircraft showing the ground under the aircraft and the #1 engine.
It
appears that the foam has pooled from the RHS but, where slides would have opened at L1 + 2? The ground is dry.
