We solve this in the two cases of two projective rows and of two projective flat pencils in a plane.
The property of the separation of pairs of points by pairs of points is projective.
This is essentially a theorem of projective geometry, but the following statical proof is interesting.
It has often been said that metric geometry was quantitative, while projective geometry was purely qualitative.
