Since the GDG base is cataloged, the implicitly referenced DSCB could not be cataloged, therefore it cannot exist in an SMS environment. As to "model data set" vs. "Model DSCB," the distinction escapes me. A DSCB is a record in the VTOC that is used to describe a data set. When you specify DCB=dsname, you are requesting that the system copy DCB attributes from data set DSNAME. This is done by reading the DSCB for DSNAME.
