John, here it is straight form Cisco text.

tm#xtocid1067224
When redistributing networks, a routing process name can be specified as
an optional trailing argument to the distribute-list command. This causes
the access list to be applied to only those routes derived from the
specified routing process. After the process-specific access list is
applied, any access list specified by a distribute-list command without a
process name argument will be applied. Addresses not specified in the
distribute-list command will not be advertised in outgoing routing updates.
I think that the key is when they say its applied to the routes derived
from the specified routing process. Meaning that in Ron's case, under RIP
he's applying the list to routes learned from ospf 1 with his command
