It does not work for NPCs for me.
What are actually x.y in this case, e.g. I would like to align an NPC with some object ? she should stand back to this object after inner cell AITravel.
MWSE is not a solution, it does not work on my rig.

Thank you.

X, Y are normal cell coordinates, such as you'd get from GetPos X/GetPos Y.
The following works for me:

"NPC"->Face X, Y

Great! That works. Actually, I was using x,y coordinates: my mistake was a silly wrong "endif" in the other part of the script.

Thank you!
