That's as may be, but he did not specify RNP AR he wrote "RNP Approach". Your common or garden "RNAV (GNSS)" is an RNP approach these days and there are plenty such approaches with circling minima. AR approahes are titled "RNAV (RNP)", which actually means RNP AR, as opposed to just RNP. This terminology is confusing but it is what we have to get used to.
"This fact sheet will focus on the most common navigation specification called “RNP Approach (RNP APCH)” and titled Area Navigation (RNAV), “RNAV (GPS) Rwy XX"....The other approach navigation specification, or set of aircraft and aircrew requirements needed to support a navigation application within a defined airspace, is reserved for complex airspace and called RNP Authorization Required Approach (RNP AR APCH) which are titled “RNAV (RNP) Rwy XX"
