If you move a brick without supershift, it will just keep moving one stud over.
With supershift, not to be confused with superstuff, will make a 32x32 baseplate move 32x32 studs every time you move it, and a 64x64 will move 64x64 studs every time you move it and so on and so forth.
Yes, it's redundant with 1x1 bricks.
