Curve, points, sphere, I carry out Split, and then I use Project for movement of points to the region of a surface. But not all points correctly move. Why?

Hello - presumably that is due to tolerances at the trimmed edge.

How? Accuracy for all edges one.
Unless it is not an error of the program (bug)?
Hello - please try setting the file tolerance to .0001, then do the trim and the Project. You’ll likely see that this works better - see https://wiki.mcneel.com/rhino/faqtolerances
-Pascal
I have created the new file and I have executed the same operations at tolerance 0.0001 - the problem remained. 
Hello - I’ve been testing V6 and it looks like this is V5 - the developer tells me there is a bug in V5 trim where the edge tolerances are not what they should be and Project misses the trim - in V6 this is fixed.
