The track numbers are associated with the whole vertical "column," not
the end of the wire at the bottom. You're not really ignoring anything,
because the current track number isn't associated with "*that* wire,"
as you describe it. The numbers in the boxes tell you where a wire
connects to...the track numbers are only a reference to where that
connection can be found (like a page number).
