I think they are trying to throw people off…. get them distracted on a supposed bungle by the Trump administration. It's a laser pointer for the cat it seems. In the end, a public meeting will take place. This letter also was careful to compliment Kim and give him props that he can brag about to his citizens. It's a way of making it look like there is discord without disparaging Kim and making him "lose face" in-front of his people.
Basically I think Kim is in on the scheme, but time (or Q) will tell.
