It's true.
To dodge the lasers, you've got to do a couple different things in each situation. It's complex at first, but you get the hang of it after a while. It worked wonderfully against Kismet on all the stages we've played at- pictochat, lylat, yoshi's, smashville.
Basically, you've got to use a combination of these listed below
instead of throwing your second pikmin in
some of your short hops. It depends on where you are in relation to Falco and his lasers, and what pikmin you've got up next. The latter is important because some pikmin throws will be used to protect your landings, while others are for hitting Falco.
FF->AD->shielding
FF->AD->quickly SHing->pikmin throw
FF->pikmin throws (usually whites)
Ex. In order to help limit getting hit by the lasers that may meet you during your two landing frames, you can FF->AD->shield instead of throwing another pikmin (unless it's a white, in which case you can use it to collide with a laser). Many people will throw out a second pikmin just to find that it arced over the laser, it didn't hit their opponent, and they were hit by the laser. Instead, they could get to the ground more quickly, shield the laser, and then prepare for another SH->throw.
Overall, pikmin are a little less spammable, but they take more time to deal with once they hit/latch and they deal more damage. When it comes down to it, Falco's lasers don't have the luxury of having many different speeds and arcs. All of the lasers, as fast as they travel, follow a very linear path. In this matchup, I'm certain that Olimar is better able to weave in and out of his opponent's projectiles while throwing his own than Falco is able to do the inverse.
