Reiterative

undefined:

A reiterative is a system (or group) in which members may split new versions of themselves that often take on their previous roles, coming into the forefront over the older member. This process may be repeated over and over again with each newest member, creating a potential group.

New members will sometimes see themselves as different versions of the older members, but they don’t have to. Both the group itself, as well as individual members within it, may be called reiteratives.

Example
A system host splits a new version of themself (or just a member in general), and that member may take on their old system functions. In the future, this new member may repeat this process. This can create an entire group of members of this variation, and this results in having members who seem to go chronologically backwards.
