Yes, the line would have to be specified before the add oneway=yes. Note 
that I did not test it. You might want to display some diagnostics such 
as the way id or the lat/lon there, but I do not know how.  (Strings 
such as ${id}, ${lat}, ${lon} would refer to user attributes, not to the 
internal attributes, as far as I understand.)

Like I wrote a couple of days ago, for bulk editing, you'd better 
extract the oneway-less motorway_links from your map extract with 
Osmosis and loading the result in JOSM. That is, if the above echo rule 
complains anything, use Osmosis and JOSM to fix it.
