It is tricky to tell for certain, the Hyakuya agents responsible for the kidnapping used the actual memory retreiver that had an effect on Asuramaru, but maybe just needed Yu unconcious to kidnap him. Thinking about it maybe Saito needs Yu out the way to ensure that: 1) the first is captured (evidently possible without Yu's help) 2) that the Demon Army is defeated utterley, again sure of success even though they have a seraph on their side. 3) Then finally to also keep Yu out the way for when Urd arrives after his delay.

Then what does that leave Yu for? Also a consideration, Saito is truly defending him, not from any of the above, huge threats as they are, but in actuality from Guren. Saito may be aware of Guren and Mahiru-no-Yo's plan and that is what he is keeping Yu away from.
