The convoluted wt teaching is, that the partaking of the remnant gives the "anointed" the right to "everlasting life" on earth (like the second Adam) ,--but then they have to sacrifice that privilege for the better hope of immortality in heaven.
That explanation does not address the fact though, that the non-partaking "Other Sheep" sooner or later will have to partake too, in order to have everlasting life like Adam, and be resurrected.
wt has never put those 3 steps in one sentence, because it too would expose their error of confusing the new covenant with the one for the priesthood and kingdom rule, and highlight the command to eat, drink all of you, not anointed yet.
