I suppose David Splane's new video would tie in good with the 2008 Generation belief and the new view that the selection of the anointed did not end in 1935.
By saying now that there may not have been anointed on earth during the past 1900 years before 1919, that gives a basis they can use for explaining why the number of anointed is increasing now: They'll just say God is filling up the spots that remained empty over those 1900 years.
In addition, if they are going back to the 2008 view on "This Generation," that means they'll say Jesus promised their would be anointed on earth until 70 C.E. but not afterward.
And the secondary fulfillment is that Jesus promised there would be anointed on earth from 1914 until the End.
