I see now.  What I mean is that a line ending without being connected does not make sense, and the default render does not show connecting vs crossing.  When I pulled this up in josm I can see a node with a connection, and apparently the physical support is NE of the connection point.  I also see them connected NE of 495.

Thanks for the discussion.  I learned something - I expected the default render to be better, but having thought about it I see it would perhaps be hard to add a little dot at connections, and more so that people who don't find powerlines interesting would find that clutter on a general-purpose render.
