Actually, the reason is that regexp matching a macro is:

  "\\\\[a-zA-Z]+\\*?\\(\\(\\[[^][\n{}]*\\]\\)\\|\\({[^{}\n]*}\\)\\)*"

IOW, brackets (even escaped) are not allowed in the arguments of a LaTeX
macro. So the first \IEEEAuthorBlockN is correctly recognized but
\IEEEauthorblockA fails.

This is not optimal, but I think it is sufficient, since, again, Org
handles only simple raw LaTeX syntax.
