I noticed others caught this too:

Quote
He was beginning to realize this Lois was a much different Lois Lane than the one who had made him Superman. This Lois must be more like his Lois; his old editor was always telling wild stories about her.
The Lois Lane who made him Superman was just like this! He just hasn't seen her go through the changes.

I like your idea that since Alt-Clark grew up without a stable family, that it will influence him. He doesn't have the patience and confidence that 'our' Clark does.
