It's not that odd when it comes to Trump. When it comes to details for something HE is doing, he goes into finite detail.
When he was building one of his resorts (i dont recall which) he had sink samples on his couch for about a year, and everyone who came into his office had to weigh in on which they liked.
He is just wired that way, I am not saying there couldnt be some other things at play also, but as a rule, Trump loves the details of things and makes it right. True leadership, taking responsibility over EVERYTHING.
