I wrote the following line in org-mode, which contains two equations.

$(Z^{*}_{m}, \cdot m)$  $(Z^{*}_{m}, \cdot m)$

But the org-mode didn't identify them as equations. Instead, it highlight
the part between the two *s, i.e. }_{m}, \cdot m)$ $(Z^{, making this part
bold. Is this a bug of org-mode or my own mistake?

FYI, if the braces enclosing the "*" are removed (like below)org-mode can
parse it correctly.

$(Z^*_{m}, \cdot m)$  $(Z^*_{m}, \cdot m)$
