That looks like a good way to patch images to me. Judging from the vide
the preview seems to be simply a "copy-paste" of the area that will be
used to patch.

Since I think the algorithm used is the same as for the Healing Tool,
implementing this tool should be rather easy. Would probably make sense
to let gui.gimp.org study the details of how to make this tool as usable
as possible, though the way Photoshop does it looks pretty optimal to me.

Let's hope someone finds the time to look more into this.
