As far as I understood JOSM is only running a generic sanity check 
(like: are all ways aligned in the direction from-via-to). Any "error" 
that JOSM or JOSM plugins are reporting are to be treated rather as: 
"You should double-check this, it could be wrong.".
I'd conside your example and the tagging you suggested to be valid. I 
don't see a necessity for the via way direction to be enforced going 
from the "from" to the "to"-way.
