Good catch! This could have really hurt if I wasn't paying attention.
Speaking of not paying attention: it turns out that "~" doesn't work in
this case. I'm guessing that since the point's BB isn't completely inside
of it's line's BB (they usually share an edge), I end up getting every
single start/end point. The "&&" operator, however, does work and appears
to speed things up.
