Jimmy it is rare to use two resisters instead of one because a board
becomes bigger
and introduces cost.

If they used one resistor in another place or places it's could have
been easier to use multiples in series/parallel where they could rather
than purchase and stock another value at the factory. I worked at a
place where we used 5532 op amps in many audio circuits and in one place
as a flip flop so we wouldn't have to stock a 74xx or 40xx just for that
one use. It was easier on the assemblers to have one bin of chips,
better quantity pricing, no sweating running out of one part kept in
smaller quantity, (insert more bean counter stuff...)
