Did Saito wake up?

Excuse me, I was just reading this passage and I came across a bit of confusion. Could you please clarify for me, did Saito actually wake up from whatever state he was in, or is there some ambiguity in the text that I might be missing? I'm really trying to get a clear understanding of the situation and I want to make sure I'm not misinterpreting anything. Thank you in advance for your help.
