"Entering a room means always moving to the center"
I unerstood the above procedure you mentioned, but while testing I'm pretty sure that at one point, instead of moving from the entrance door to the center first, I managed to move straight to another door, diagonally. I can't test it again here at work, but I might find the time tonight to see if I can reproduce this.
Maybe I was wrong and just quickly moved to the center and then to the door, I'll see.
