Do they still believe in overlapping generations?

I know it started with the end in 1914, then Jesus rule began in 1914, then the end in 1925, then 1975, then the generation of 1914 will not pass away, then overlapping generations. But I think read somewhere that they believe now that all the anointed can die before the end comes? Does that mean they abandoned the overlapping generation teaching that fast? And after this set of GB die, the following set will not be anointed?
