Here is a link to a small video that demonstrates the movements on the first layer:

This is a simple model to test the quadarticity of the printer, and in this case it's not critical, but in more responsible products I'd like to have a smooth first layer, which is difficult with jumps like this.
And frankly I don't see any reason to depart from the usual line to line filling and jumping back and forth.
