That was my first reaction when I read it for the first time and I still hold to that. Asmodean knew who she was, and was surprised to see her, of course. Moiraine balefired him and left his last words hanging. It was one of the wishes the snake/fox people granted her and now she has to wait to be rescued by Mat. I will be disappointed if it doesn't turn out that way. 
Thus it's not really possible for them to fulfill such a wish or to get Moiraine back to Finnland once she returned to the Westlands. It also doesn't make much sense that Moiraine would wish to kill Asmo, especially since Moriaine knew that she would be captured by the Finn. If she had a shred of intelligence, Moiraine would certainly wish for her freedom like Mat did. It seems self-evident that Moiraine didn't get any wishes, but was immediately captured as an intruder who melted the doorway, similar to Lanfear.
Finally, RJ said that Asmo couldn't be transmigrated because of how AND where he died. If Moiraine balefired Asmo, this would already prevent transmigration like it did in Be'lal's case. Therefore Asmo certainly wasn't balefired.
