Probably cause it's kisuke and he doesn't do things that makes sense to the common person. Isshin probably asked him to allow himself to hand it to ichigo with that reasoning to not draw suspicions. I just can't see any logical reason, if i was kubo, to have it that Ryuken would create something to protect ichigo before he ever made an appearance in the canon plot. Oh well, still disagree it's ryuken. :P
