primary and secondary power factors are equal

Basically yes, it's the reflected impedances. The transformer, in this case, is nearly a perfect device so it has little effect on the real or reactive power going through it. So the load on the secondary is reflected to the primary with no change in power factor. To change the power factor would require a change in either the real or reactive power.
