Hi Andreas,

Yes, that is the expected behavior.  Org is much pickier about when "$"
can be a math delimiter than "\( ... \)".  The reason is that "$" can
also be used as a regular symbol in Org documents; when it is, it should
be *not* be exported as a math delimiter to LaTeX, and distinguishing
non-math-delimiting from math-delimiting uses of "$" is not a trivial
matter.

Thus, when in doubt, use "\( ... \)".

Best,
Richard
