Comment (by strk):

 What happens after this step is that the line (now in red) is further
 snapped to the existing nodes, which moves it further left, to intersects
 with the green.

 I guess a solution here could be to improve snapping so that subsequent
 snapping operations would not move the line anymore.

 This might also be seen as a bug in the GEOS snapping routine.
