Does anyone understand this "fad" of MIG welding with spot, spot, spot, spot, spot?

Why not just set the correct voltage and wire speed and do a weld bead?

I get that maybe you cannot get around the circle in one pass without a positioner, but certainly three arcs will do.

I see it on many yt videos and wonder is it just one of those "I learned to weld on yt" things?

Thanks,
Brian
