Exactly. Though even for a "stuck-at-first-level-monk-NPC", I think it is a feat of very doubtful utility; whenever he could use it for the
possibility of gaining an extra attack on
another target at no penalty, he could instead flurry
without having to spend a feat, making two attacks even if there is not another enemy nearby, albeit at a -2 penalty to both.

Though I fully agree about the "feat overdose" we face (and not only regarding feats, unfortunately), I do think there would be an exclusive niche for this one if it had been properly done.
Pretend it required a standard attack action (still giving up all other attacks) instead of a full-round action, for instance: now we have a feat that allows that spring-attacking monk to dive in between two mooks, jump into the air and kick both in the face, tumbling back right after doing so -
even if she didn't drop any of them.
Hmmm... I smell a house rule reviving an old feat in my games.
