I have as a request in the current Lightworker Healing Protocol: “Carry out these sessions in perpetuity throughout the current life as well as all past, present and future parallel lifetimes, their future extensions, and all future incarnations, commencing with their return to the womb.” Is the phrase, “all future incarnations,” actually redundant? I was thinking it might be needed in case a new incarnation was started by another projection of the soul.

That was the purpose and it was in reference to envisioning the possibility there might be a new incarnation launched by the soul at an overlapping point with the current soul projection incarnating on the planet. So any rewording to take into account this possibility will cover what you intend here and anything making it more explicit will have some advantage in clarity for the practitioners.
