Right.  The macro takes your exact triangle, and moves it from right where it
is, to exactly where it would be if you moved it there with some unknown
combinations of rotations and translations.

I did wonder what would happen if I jimmied some of the target triangle
coordinates, and yes, the triangles got moved - but I have yet to quantify
exactly how.
