Does this mean format increment is unnecessary and also lyx2lyx is working well?
I am not expert on mathed parsing, Enrico would know.

I think the point here is that the math stuff is just stored as LaTeX. There are not LyX-specific constructs in it. So the LyX file looks like:

\begin_layout Standard
\begin_inset Formula $x^{2}$
\end_inset

The LyX insets (e.g., superscripts) are created as the Formula inset is parsed. But there's no sign of them when it's written to LyX. It's just written as standard LaTeX (with some extra braces, perhaps).

Hence, the Intertext inset is simply written as \intertext. LyX 2.4 will read it and treat it as ERT, in effect. But LyX 2.5 will create an Intertext inset when it reads it.
