This is correct. The final nuclear state ("fragment" or "residual nucleus") resulting from an inelastic cascade is passed out as one of the secondaries (i.e., a G4Ions). If your physics list includes G4RadioactiveDecay, then that new G4Ions will be properly decayed in the event when it is popped off the tracking stack.

This is also true of other inelastic hadronic processes, such as neutron capture or fission: the outgoing nucleus (or nuclei) become independent particles (G4Tracks), which, if radioactive, will be decayed by RDM.

Doing this ensures that all radioisotopes are treated properly and identically across the simulation.
