Lol, yes in a way.
You'd use it every time the preceding bar/measure isn't 4/4.
For example you have a bar in 7/8 followed by one in 4/4. If the grid is set the quarters you'd see 3.5 beats in one and the other beat markers would be offset by 1/2 a beat. That box stops this and has your bar start on the beat.
