The pointless thing is even trying to make sense of it at all.
Whereas it may be contrived to convey a sense of urgency now, in a few years, the overlapping generations can be extended out to Jesus evidently meant two overlapping generations of 70-80 years each. At that future possible evidently, if one of the anointed was BORN in 1914, died in 2014, an upcoming anointed born before he died would be around on earth during the great tribulation. Could potentially be a 200 year overlapping generation.
