in PTv1, one relation is used for all forward and backward route.
therefore ways that is in use only in one-way route must have 
forward/backward role.

in PTv2, the previous relation is splited in 2 relations. one with all 
ways used in forward, another with all way used in backward (and we 
group together with a route_master).
therefore all way have a empty role (= no need to put all with forward, 
it's always the case in PTv2)

yes maybe that should be better explain in the wiki
