Ok, I just don't see the purpose. It's a freaking swivel base. Why?

Keeps the vise in a known position on the rotary base, so the fixed jaw
is
always at a certain radius from center.

I'm not sure I do it, but I can see its usefulness, especially if one
were
doing a lot of one particular part (not in batches) over several
changes
of
tooling and fixturing.

The base was keyed to the table. Not the vise to the base.

Keeps the degree readings relative to the table axes and not a random
orientation.

Makes sense. I can't mount it square on the no name anyway though.
