Yeah i think they're both pretty good in a fight and just knew that they had no reason to rejoin the fight after getting smacked out of it temporarily cause they know just how good Team RWBY is (at least Sun does) so in typical man fashion decided "welp, they don't need us anymore lets get some chow". As for Sun's trick there, might take more focus or maybe its more effective against other enemies, ya know, the ones who aren't massive armored mechs. Even if its not, i can think of many ways to use that in a fight, distractions and stuff like that but i get the feeling its more useful than we've seen because its Sun, he doesn't have a useless trick
