At this point both Rebel and Fritz >>were acknowledging white's position is lost. I wonder if 3 Rh-f1 might last a little longer? I can't see what Rd3 is supposed to achieve. But apart from that it just looks like a typical position designed to make null move look bad. Fritz is a famous null-mover. Rebel is claimed not to use standard recursive null move, but probably uses some other pruning scheme that has the same problem here. Junior is supposed to do no null moves for the first few moves. Perhaps it would understand this.
