I probably just misremembered the positions of things when describing it. Looking back at the original comment I was responding to, Marie75020 was one step short of being able to leave the room, not one step short of the exit space, so I clearly just had a brain-fart when answering that one, and mentally put the star one space back from where I thought Marie was (obviously I didn't have the star there anymore myself to check it). Mea culpa. I'll update that comment so it doesn't confuse people ;)
