Yeah the way Flow currently works is by going from the UV space of the base surface into the UV space of the target surface.

So it inherently works in a sort of 2 dimensional way, inside the UV space of each underlying surface and not really paying attention to any trim curves that may be marking areas of each surface as a hole or cut away area.

Again, I think that the new projective option coming in the next beta is going to be more like what you want:

The current way Flow works you would use it more for applying a pattern that goes across the entire target surface.
