It can't but it ACTS like if you had 100% spillover.

The act of spilling over is a symptom of db sharing device with data.
If you have no dedicated device, then ALL db shares device with data.
If you have a db device and it is too small for the whole DB, then
PARTS will spill over and you get a notice so you can decide how to
act.
The spillover is not the problem, it is a symptom of "I have more DB
than my db device can hold". No DB device means "immediately I get the
same effect as 100% spillover".

Think of it as a small glass of water spilling over when you over fill
it. If the glass is small, lots of spillover. If the glass is missing,
ALL water "spills over".
