Org export LaTeX: Multiple dashes in ~code~/=verbatim= turn into wrong number of dashes

Question

As shown in the image, ~--~ becomes \texttt{-{}-} which turn into 2 dashes in the PDF.

Reason behind seems to be: LaTeX thinks -- as a single character (TeX-ligature for en.dash). And, {} in -{}- separates the two. (take a look here). So, it seems that org wants to export multiple dashes into same amount dashes (no ligature). Plus, Text in the ~code~ and =verbatim= shouldn't get TeX-ligatures:

Text in the code and verbatim string is not processed for Org specific syntax; it is exported verbatim.

By these logic, shouldn't ~----~ become \texttt{-{}-{}-{}-{}-} (actual 4 dashes) instead of \texttt{-{}--{}-} (dash + en.dash + dash)?

                |      \end{enumerate}                   |     \end{enumerate}

I'm guessing what's going on behind the curtains: it replaces -- with -{}-. So 4 dashes (----) has 2 -- so each couple get replaced with -{}- finally forming -{}--{}-.

• Is my reasoning right?
• Is this legit bug?
• Or, Is there any reason behind it works the way this is?
