Comment:

 Yes, this is expected. Points are compared WRT machine epsilon scaled by
 the greater coordinate absolute value. Currently it's not possible to pass
 user-defined epsilon value into algorithms which could be used in Point
 comparisons. It'd be possible to implement custom coordinate type with
 comparison operator using greater epsilon but this way this comparison
 method would be used in every case, not only when Points were compared.
