I agree that it's unclear why one would ever want to do this, but LaTeX does allow it, and so LyX allows it, too. Maybe if you had a really long equation that needed to be part of the title, you'd want to do it that way. I do see the difference you are talking about now, though. In both cases, it looks like a displayed equation immediately follows the section title. However, in one case, it is actually part of the section title. In the other case, it is not, but is in a separate paragraph. Here is the LaTeX output: \section{This $$x=y&=$$} One two \section{That} $$x=y$$ One two. Note that I've simplified this a bit, to make it easier to see what's happening. The result, in the PDF output, is that there is additional whitespace above the equation in the second case. This is LaTeX's doing, and has nothing to do with LyX itself. If you wanted to counteract this, then you'd have to put some negative vertical space in there somewhere. See https://tex.stackexchange.com/questions/763938/correct-way-to-reduce-space-above-displayed-equation-which-shows-right-below-sec for the way to do this. It is not trivial. The difference is not completely obvious in the LyX display. But if you look closely, you'll see that there is additional whitespace above the equation there as well. If you had pilcrows displayed, then it would be clearer.
