If you were referring to the bit about Rachel Summers, I'm pretty sure Jean was "dead" in the comics as well when she traveled to the present in the comics as well.
Yes indeed. Jean was 'dead' in the comics at the time of Rachel's arrival by time travel.
There would need to be an explanation for why the time traveller stopped off in the present day to recruit more X-Men to go the 60s. Presumably, because the future X-Men were all dead and the traveller wanted to assemble a team/back-up for the mission.
