I added the point count check according to git blame and I don't remember
why but I agree is doesn't look like it makes sense to me.  I think this
lasso is lightly used based on the volume of questions we get about it.
 One reason it may be lightly used is because it is hard to work with.  If
we can improve it, even changing functionality,  I would be in favor.  Eg,
allowing the same Lasso to handle repeated selections makes sense to me.
 If the change looks too onerous, we could call it Lasso2 and deprecate the
former.
