Thanks for reporting!
So, the docstring was erroneous at the end.

Can you try to test the attached patch?

Subject: [PATCH] org-cdlatex-mode: Fix regression from f01390cf05

* lisp/org.el (org--math-always-on): Rename to `org--math-p' and only
override `texmathp' when current command is `cdlatex-math-symbol' or
when we are inside Org LaTeX math fragment.  Only these two scenarios
are the places where `texmathp' may not work properly in Org files.
We must not return t outside latex fragments as initially suggested by
the docstring because it would break, for example, `cdlatex-dollar'
command.
(org-cdlatex-mode): Use the new function name for advice.
* lisp/org-compat.el (org--math-always-on): Declare obsolete.
