Nope. This is a bug.
It happens because LaTeX fragments are processed in temporary buffer and
all the buffer-local variables you set in the original org buffer are
discarded.
The fix is attached.
Nicolas, this kind of error might be present in various places of export
library. You may want to fix it in more places than what I propose in
this patch.
Best,
Ihor

Subject: [PATCH] org-html-format-latex: Preserve buffer-local settings
* lisp/ox-html.el (org-html-format-latex): Carry over buffer-local
variables when create LaTeX images. Use `org-export-with-buffer-copy'
instead of `with-temp-buffer'.
