That sums it up well.  One reasoning behind the frontend/backend split
is the ability to team multiple backends together and/or have multiple
frontends.  This enables you to have more tuner cards or disks than
you can fit in a single computer, and/or a frontend for every room in
the house.

One situation that seems common is to have a big case (e.g. CM
stacker, rackmount etc) with multiple disks (raid array) and multiple
tuner cards and a powerful processor.  It would schedule, record,
transcode & store media.  This would typically sit in the garage,
under the stairs, in the spare room etc.  There would then be a small,
low power, quiet frontend for each tv.

Perhaps a case like this for a backend:
vs. something like this for a frontend:

It is definately possible to have a combined frontend/backend and as I
only have a single TV and not a whole lot of spare cash this is the
route I've gone.
