The default value for :matches is ("begin" "$1" "$" "$$" "\\(" "\\[").
It looks like the value hasn't been touched in a long time, and that
AFAICT the "begin" should cover "align" just as it covers "equation".
And I'm not spotting any recent changes on Org's end that should affect

On master, maint, and the commit matching your reported version
(e62ca4), I tried org-inside-LaTeX-fragment-p within each block of your
test file, and it returns non-nil, including in the align and align*
blocks.  So I dunno...

Could some org-cdlatex users out there give the test file a try?
