This is how false narratives are born. It sounds plausible so let's pretend it's true even though there is absolutely no way of us knowing what Conte was thinking at the time or what the discussions between him and our board were.
You're free to believe Conte wanted the summer off, at the time there were reports of "lack of ambition" and now he has the job he's not going to confirm that, is he?
I also assume you believe that Conte hasn't spoken to the board about possible January signings?
