I guess you are talking about the geometry view and not the highway view.

Long ways are a potential problem if you have long segments with no nodes in
it. One problem is when you draw a small part of the map that has a line going
through it but no nodes in it (because they are all outside), the line might
not show because the software doesn't recognize this. You can run into this when
using Osmarender for instance. Another problem ist the projection. Straight
lines on the earth are not necessary straight lines in some projections. They
should show up as curves. But if you don't have enought supporting nodes, you
don't get nice curves. This view warnes you that you might run into those
kinds of problems. It doesn't mean that your data is wrong. It means that in
some cases your data might not be interpreted in the right way.
