For instance for the relations named ‘Icknield Way’ and ‘Chiltern Way’, I would like a way that is contained in both relations to be named ‘Icknield Way Chiltern Way’.

set route_display_name='${route_display_name}'

This will overwrite the old route_display_name, you need to
add it.
For example what I do:
(route=foot | route=hiking) & 
        (osmc:symbol=blue | osmc:symbol ~ 'blue:.*') &
        (name=* | osmc:name=*) &
        (network=iwn | network=nwn | network=rwn | network=lwn) {
        apply { set route_blue='$(route_blue):${osmc:symbol}'|
                                 '${osmc:symbol}';
                set route_blue_type='${network}';
                set route_blue_name=
                    '$(route_blue_name), ${osmc:name} (${distance})' |
                    '$(route_blue_name), ${osmc:name}' |
                    '${osmc:name} (${distance})' | '${osmc:name} |'
                    '$(route_blue_name), ${name} (${distance})' |
                    '$(route_blue_name), ${name}' |
                    '${name} (${distance})' | '${name}'
              }
}

So route_blue_name contains afterwards a comma seperated list 
with all osmc:name of all routes.
