Nope, he's short enough that if you don't pummel while he breaks out, he'll air release every time.
Then you boost regrab, and snap a couple pummels, lather, rinse, repeat until you get close to the edge, then you can do whatever you want to him (dthrow, fthrow, etc.).
It could really come in handy, having something that makes his grab against falco much more monopolizing will obv. make him play in a way that is more predictable (aka avoid the grab ****).
@jbandrew: it was answered earlier, but for a repeat, it's a dash attack canceled dash grab (you hit down on the c-stick and IMMEDIATELY hit Z afterward). If you get a dash grab that gets slightly more range, you did it right.
You can also dash attack/DACUS after air releasing falco, although obv. the grab is more rewarding.
edit: another question, does anyone have data on the trip %'s on ftilt1? I really want to know about how many times I should be poking w/ that move at a given %, since obv. that trip = goodies afterward (grab/utilt)
