In Org mode, there is a significant difference between \alpha and
\(\alpha\). The former is natively fontified (with `org-pretty-entities'
set to t) and natively exported to HTML/ASCII/ODT/etc. In contrast,
\(\alpha\) is very generic and Org mode has to invoke LaTeX, and
transform the contents into an image to render it. This includes export.

So, plain \alpha entity is generally more universal when in Org mode.

Further on the topic of the advice, the original texmathp has no idea
about Org-mode's syntax. If you have something like

Verbatim text: =\(= followed by \alpha \)

Then, (texmathp) will return non-nil on "\alpha" disregarding Org mode's
syntax.
