If Kolyada wants to compete against Yuzuru, he would be even happier to be able to compete against him twice than once.
Apparently according to someone from Kolyada's GS thread, by "waiting for Hanyu's decision" not necessarily meant that he will wait which GP Hanyu would pick. But he meant whether Hanyu would decide to join GP series at all (due to his health condition), since if Hanyu pass GP, Kolyada would be in 1-3 seed instead of 4-6 seed. From this it seems it has nothing to do with if he wants to compete against Hanyu/avoid him at all.
