The TRD Pro skid comes up higher than the standard skid which is why the SSO Bumpers have to be a little different to accommodate them. This looks like someone selected the TRD Pro skid plate option when ordering and installed it on a vehicle with the standard skid plate. Mine ('14 Trail) sure doesn't have this gap, and haven't heard of others with this issue.
EDIT: That video is NOT the SSO bumper. He mentioned it was the Warn Winch Bumper
