There appear to be legend variants. This one has only SAN PAVLVS:

So, possibly the same type has SAN PAVLVS, SAN PAVLVS A .and SAN PAVLVS AP as legend variants (never mind that Paul was not generally considered to be an apostle

)
The best place to confirm is CNI, which usually has a fairly comprehensive list of such variations.
