VSR end of Life-

there are two surfaces of degree 3
in fact it is only one surface that I divided in two with the split command
the continuity between the two surfaces is perfectly continuous.
but by applying the matchsrf command on one of the two surfaces
the distribution of the points corresponding to the curvature is destroyed and the continuity degrades a little, the points take the shape of a crossing in opposite direction, like an x .
what is intriguing in this example is that the isoparametric direction of the target surface in the U direction is not twisted.
normally the surface that undergoes the operation remains absolutely straight, especially for the two choices (auto )and (preserve diraction)

I think this is the same (10 year old) bug I pointed out here:
