yes, these nodes are likely mistagged, I usually tag nodes aside the road with
traffic_sign=maxspeed 
maxspeed=50 (etc.)

and on the highway
maxspeed =50
source:maxspeed =sign

tagging traffic signs on the road (unless they are road markings or maybe overhead signs), is strange as well, because you typically don't find signs on the road. In case of overhead signs they should get a higher layer and not be part of the highway.

it would not have to start there (because of repeating signs)
