The way coderefs appear in the code are completely configurable using
org-coderef-label-format ("(ref:%s)" by default) and using -l src code
switch.

If you examine 12.6 Literal Examples section of Org manual, you will see
that coderef links are exported specially:

       In literal examples, Org interprets strings like ‘(ref:name)’ as
    labels, and use them as targets for special hyperlinks like
    ‘[[(name)]]’—i.e., the reference name enclosed in single parenthesis.
    In HTML, hovering the mouse over such a link remote-highlights the
    corresponding code line, which is kind of cool.
