Nope.
Why would Peter remove his mask in the library? Is Peter psychic, did he know he was going to come across Connors in human form in the bathroom?
If you watch the previs for the school/library battle it makes sense.
Peter is knocked into the shelves by the Lizard, like in the movie... but then, the Lizard comes towards Peter. Which actually makes sense, why would the Lizard just suddenly take off (like he does in the movie) when he has Peter almost knocked out? Because he was going to turn back into Connors? Hm, maybe.
Now I think they shot this but never got the effects for the Lizard complete... or something like that. Because in the movie once Peter's slammed against the shelves, you can see that the mask on the suit is ready to be taken off. But it never is.
Then Peter finds Connors in the bathroom, like in the deleted scene we've seen.
