I think some people are getting confused as to where blivvy can stop, It can stop on the lift hill, it can stop on the turn around and the approach to the drop (there are block breaks and grip wheel up there. But it cannot stop on the Reverse Chain Lift (the holding point).
Even if the ride e-stops as the shuttle is on the reverse lift, the next block would already have been cleared (the break run) before it was allowed to proceed onto the holding point. Therefore even if the e-stop is enabled it is still safe for the train to drop and continue to the break run.
It probably stops at the top or somewhere on the lift hill at least once a day.
