You would need to delete the surface you've currently got, then run Rebuild on the curves that you're using, and then build the surface again.

For most cases it's not really an issue having things broken apart into different faces, and in some cases it's actually better since you can separate things for some localized work.

But Blend is an exception - for the particular case that you plan to use Blend later on then you would want to run Rebuild before constructing the objects you want to blend between.

In the future I'm going to be overhauling Blend so that it will be able to work on a longer chain of connected edges rather than just between 2 at a time, and at that point it will be much less of an issue.
