IMHVO, this is a nonsense argument (not blaming you). A way
representing a road represents, at this micro level, an area the width
of the road. So, when a footpath and a road connect, this doesn't mean
that the middle of the footpath and the middle of the road connect: it
means the *edge* of the footpath and the *edge* of the road connect.
By the same reasoning, a landuse area sharing a way with a road means
that the *edge* of the road connects with the edge of the landuse
area.

It's particularly appropriate when the boundary of an area is defined
by the road or river in question - we're capturing the actual
definition of the boundary, rather than another approximation of it.

Oh? How so?
