It was done to make it look more passport like -- to convey a false sense of citizenship -- and to use it as a way for some notices/endorsements to be placed on it for when dealing with some Indian authorities. I don't know if the OCI booklets have been marked up for those who needed to get identification numbers and additional authorizations of sort after arrival in India as an OCI, but maybe some have.
