It seems that Mapfactor, like all OpenStreetMap router (as far as I know), does not manage restriction relation type: "from-way=>via-way=>to-way". Although rarely used (0.8%) the "via-way" instead of "via-node" is the proper scheme for example when tagging no-u-turn restriction for dual carriageways on crossroads.
Same relation in a different situation also found here:
Hi ualios, I can confirm that currently we convert only from-way, via-node, to-way ... and at the moment it does not have very high priority, sorry Martin
