I don't think you can with current Jade capabilities

External-procedures are a mechanism used to introduce externally-provided
extensions (usually provided by the implementation, i.e. Jade) into the
style-sheet namespace. For example, an external-procedure might be used to
query the username running Jade.

To get different margins for odd and even pages, you need the page-sequence
flow object class, and use the repeat-page-models characteristic. You also
need an implementation which supports all this.

You probably saw a reference to external-procedure in the context of
if-first-page or if-front-page, which are Jade extensions and therefore are
external-procedures.

If you really need it, you can add such an extension yourself (or preferably
add support for page-sequence).
