RAJUMATHEMATICSMSCThe two sentences are not in conflict. Deferral of 365 days is after the release of a given version:
365 days after the release of 1809, the PC installs 1809
365 days after the release of 1903, the PC installs 1903
365 days after the release of 1909, the PC installs 1909
The new default (no deferral) as I understand it ends up upgrading once per year:
16-18 months after the release of 1809, the PC installs the then-current version (1909) in spring 2020
16-18 months after the release of 1909, the PC installs the then-current version (2009) in spring 2021
Left unclear is how to turn it off, to revert to the default. I have read setting DeferFeatureUpdatesPeriodInDays to 0 reverts to the default behavior but my testing with PSWindowsUpdate seems inconsistent:
DeferFeatureUpdatesPeriodInDays = 150: feature update 2004 not detected
DeferFeatureUpdatesPeriodInDays = 0: feature update still not detected
DeferFeatureUpdatesPeriodInDays = 1: feature update IS detected
DeferFeatureUpdatesPeriodInDays = 0: feature update IS STILL detected
Delete DeferFeatureUpdatesPeriodInDays: feature update IS STILL detected
DeferFeatureUpdatesPeriodInDays = 300: feature update is no longer detected
DeferFeatureUpdatesPeriodInDays = 0: feature update still not detected
