Well he probaly knew there was a chance he would be compromised all double agents know that.

But really i can't think of another abilty in bleach that does that. So he could not really have legittme forseen the fact that he would be bound to Yhwach in that way. The only other thing i can think of in bleach that bounds ones soul/life to another is that thing Urahara did with Isshin and Masaki but that is no where close to the level Uryu is bound to Yhwach.
