Around here, mainly to keep the leveling wedges from falling out, and lets
you get away with actually using all those drywall screws you have on hand
from another project. ;)

IME, using the bottom screw strips helps in pulling the cabinet tightly
against the wall, helps with rigidity of the unit, and aids in leveling a
line of cabinets when part of a wall of cabinets fastened together.

Fastened thusly at the TOP screw strip, you can use just about any type
of
screw, drywall or otherwise in the lower screw strips and the cabinet
will
handle all the weight for which it was designed.

What is the use of the lower screw strip? The upper one bears the
weight, keeps the cabinit from falling. The lower would just keep it
from lifting off the wall, which it would have to do against gravity;
Most wall-hanging cabinets from furniture shops come with only the
upper mounting option...
