Justin,
Actually RIPv1 supports TWO masks.
First is the main network mask. All interfaces should
have it.
Next is 32bits-length mask or end node mask. It
is applied if router receives an update with network
number that does not fit first(main) network mask.
So I can NOT see anything ODD.
Regards,
Vladimir.
