maybe I am wrong here, but the thrust washer they speak of is actually a thrust bearing, correct?
Technically it is a thrust bearing...

it has roller bearings inside it?
No. No roller bearing. Only the bronze/steel/bronze combination.

Bronze is not generally placed against bronze in a high pressure application. The friction created if there isn't enough lubrication can cause the bronze pieces to try and stick to each other. There is usually an iron, steel, or hardened steel face mated with a bronze thrust washer.
