It's not a problem.
Once the third row is almost next to the platform, the vehicle hits a trigger point on the floor next to the track. This tells the door to unlock and open. As soon as the door is all the way up the lap bars unlock. The vehicles then continue moving until they reach the end of the platform. If a vehicle is in the second unload zone then it stops in the first unload zone. The vehicles have always done this.
What you saw was not a Ride Stop, only a Station Stop. It's easy to reset so no big deal there.
And while you think the TM could have been nicer, the man did present an immediate safety hazard. And safety ALWAYS comes before courtesy, anywhere. The only way sometimes to keep somebody safe is to shout a command, or be very stern. I know this from experience.
