I don’t see any reason why that would have changed if not to get rid of the love-magic or at least call it into doubt among the readers. Of course, a blank map does not correspond to a blank territory; it could just be making Lily act more rationally.
Not clear if we still have the love-magic in the MOR-verse, given that Lilly’s death went down a little differently (she tried to fight back).
