I would guess that, yes, this is the intention. The example you point
out is only minorly aesthetically displeasing. But if links were
rendered on top of unclassified roads, the situation of a link merging
into an unclassified (rather than passing through) would look much
worse. Example:

Granted, links don't feed into unclassifieds as often as they do
higher classifications of road, but it still happens a lot.
