No, it does. pandoc is an (incomplete) parser that converts latex to 
context. So, the latex snippet is converted to context snippet and read 
back.

But seriously, if you want to read LaTeX commands, the simplest way is to 
write the "converter" in TeX.

\let\textbf=\bold
\let\bfseries=\bold
...
etc.

An easier solution might be to restrict to GELLMU aware commands and use 
GELLMU to transform LaTeX to SGML and then just write a Context XML parser 
for that. But this is way OT here.
