Everyone else has given excellent technical reasons (off loading,
various spare hardware, network/storage issues), but here is a not
so technical real world reason:  I use satellite.  That would mean
running 4 wires into my living room to accommodate 4 different tuners.
Running wires in the house is a major PITA.  I have two wires where
I need them already.  I set up a slave backend in another room also
with two connections and I'm off and running!
