With CSRs, hosts in different subnets can have a direct ATM connection.

You don't have to make your subnet logical to put two physically
distant hosts in a sigle subnet.

So, unless you intentionally want to make your routing inefficient,
CSRs are put on physical border of contegeous IP subnet and the
path over CSRs are the optimal.

And, if you intentionally want to make your routing inefficient,
then, you can get what you want.
