Yes, yes they do. Wolf did a lot of naive, if really unexperienced things in the film he stars in. If the Aliens were any like the precedent films, the job would've been hella more difficult, and probably the Predator would be dead halfway through the film (but would anyway activate the wristbomb, thus delivering the job anyway). And no, I'm not talking about Alien/Predator strength/qualities being superior/inferior to the other. Other Predators in the place of Wolf would do a much better work. And, any other Aliens would give hell in Earth to Wolf. He turned his back on the Aliens. He held 2 by the neck (without those reacting) and was going to shoot one point blank (and we all know what shot+point blank+Alien means, don't we?), not counting he left half-a minute to an opponent to strike. The Predalien didn't attack by any means during this timespan, but put solely as an example the A3 Runner Alien in its place. Would the situation be the same? Hell no.
