I ran latexdiff on the following two files:
$ cat test1.tex \documentclass{article} \begin{document} \begin{equation} \left\Vert [y] \right\Vert_y \end{equation} \end{document}
$ cat test2.tex \documentclass{article} \begin{document} \begin{equation} \left\Vert [y] \right\Vert_x \end{equation} \end{document}
I ran the command as follows and got the following output in the difference file:

This doesn't happen if the inside brackets are replaced by parentheses or by \lbrack/\rbrack, so I suspect the issue is that the [y] is getting parsed as an optional argument.
