I'm not sure you can jump to that conclusion from his post. I mean, a lot of the reasons I like 5e is because of aspects that hearken back to B/X. That doesn't mean I want 5e to be just like B/X, or that I'm going to be disappointed if it doesn't out-B/X B/X. It means that I want 5e to have the things I like from B/X, not have (or be able to easily remove) the things I don't like from B/X, and maybe have a few new things to enjoy as well. (For that matter, all that goes the same for 4e for me as well.)
Being able to play 5e in the style of your favorite previous edition is supposed to be a selling point of 5e. And that includes 4e.
