Ra and Q'uo have said that harvest requires death, yes. Now, they have not gone into too much detail regarding the nitty gritty details of harvest (in my opinion this is on purpose, probably something to do with Law of Confusion or something similar), but it appears that the actual harvest does not occur on our physical plane. It appears that the actual harvest itself (walking the steps of light and so forth) occurs in time/space. For an entity to experience time/space, that entity must have left the physical realm (time/space is the realm that "heaven", as we humans like to call that particular experience, resides in).
The very debatable aspect of all of this is whether there is some mass harvest that everyone undergoes at the same time, or if the harvest is on an individual basis after a person dies from whatever they die from in this incarnation. Ra and Q'uo have never given any straight answers on this, so it is up to the individual to decide which scenario resonates with them personally.
