Technically, Clark doesn't remember her seeing him use his powers in Blank
Yes he does, his memories were restored to him before Lois and the Sheriff walked in on him displaying his powers.
I do agree that Infamous will be more of a true test of how Lois reacts, especially since he will be telling her before everyone else finds out
But this isn't a fair test either. The reaction would go along with the fame she'll be getting from him. She'll become the star reporter because of him so wouldn't this taint the reaction's pureness?
It's like observing a kid getting all the attention because of the toy he's playing with, and when you finally get the toy you try to get the crowd's attention. If you do get it, you love the toy, if you don't, you tend to hate it. Regardless, it wasn't the toy you wanted but what you get from having it. It'll be the same thing for Lois.
Her reaction/ acceptance of Clark is very different when in one situation she can get something out of knowing, then in the situation other's are in and she must keep it to herself.
The only why this would have been a true test, is if Lois found out by reading the article then writing it.
No, he's not asking her to keep it a secret, but he is, in effect, making her the "expert" on his situation
That is not true either because once outed, Clark will tell the people himself, not Lois. There won't be a need for Lois afterward considering the crowd gathering around him, wanting to get to know him and Lois is no where in site.
the one that people will go to in the future for information on him
Trailer hints that this isn't the case, again people going to him, and other reporters going to ask him questions directly then going to Nois Lame.
Clark may have gone to Lois to break the story, but that doesn't mean people are going to expect Lois will be getting the follow up.
