In plain terms
The Chinese design shields the satellite parts from radiation during the climb to high orbit, using the tug itself as the shield. It also plans to replace the tug's own solar panels in low orbit, along with refuelling it, so that the tug can be reused.
The claim as recorded
CAST's MMR-SPS engineers the Van Allen belt radiation problem explicitly, and with a mitigation absent from every other architecture in the source register: "The impact of Earth's radiation belt on the SPS modules during orbit transfer is reduced by the protective shield of the interorbit transporter." The transporter's own solar arrays are treated as consumable and are replaced in LEO between trips.
Scope and limits
No dose figure, no shield mass, and no quantified power-loss saving are given. The claim is that the mechanism is designed for, not that its effectiveness is demonstrated. Whether a shield heavy enough to matter is mass-affordable is not addressed in the source.
What it assumes
No assumptions are recorded against this claim.
Where it comes from
PDF p.10 (index 9), verbatim: "The impact of Earth's radiation belt on the SPS modules during orbit transfer is reduced by the protective shield of the interorbit transporter. Moreover, the interorbit transporter can achieve long-term reusability through propellant refueling and the solar array replacement in LEO."
