So what?
This tag indicates that the segment of the street is checked and there
is no legal limit visible.
If this situation comes from a mapped bridge or some other (unmapped?)
thing is no difference.
It says: As a mapper i do not have to walk there and check the sign, as
someone has done it (and found none).

QA tools should only check ways under a bridge for this tag, but should
not warn if this tag is at an way without a bridge.
