Narrative:

When ground crew was ready for pushback they announced to crew to 'release brakes because we need to pull you up on the tug.' this was a newer model tug in where the aircraft is pulled on to a hydraulic plate by an attached strap to the nose gear. While this request certainly makes sense; it breaks with pilot SOP of only releasing brakes when a clearance has been received.
