Interfaces in route process - redistributed

If a requirement is stated as "Only one routing protocol can be active on
any interface"; is redistributing that interface into another protocol a
violation of the requirement? From reading a previous thread, I was curious
and concerned about this. For instance, in the example below, E0 is part of
the Rip process and the S0.24 is redistributed into it and vice versa for
EIGRP. Is this an acceptable solution or does this create the instance of
having two routing protocol active on an interface?
