Knowing who is attracted to whom and why they are or are not acting on it can give you a lot of useful information...
1) It tells you nothing of why they are or are not attracted. It can only tell you whether they will act on their attraction given the opportunity.
2) I guess I failed to indicate that it only applies to the caster--you can't tell if A is interested in B or not.
