That is a good point to remember. This is only useful for supply rejection.
It has nothing to do with regulation or reference. It should be noted that
depending on the current your circuit or IC pulls, you will get some kind of
voltage drop across the resistors. Further more, this is only really
suitable for circuits which pull a relatively constant current. A circuit
that would pull and intamitently high and low current from the system will
probably suffer problems due to the changing voltage at the other end of the
resitors. And just for succinctness, If you're running a single supply you
only need one resistor. Never put a resistor to ground. Well there are
exceptions but that's beyond the scope here.

Be absolutely Icebox.
