better documentation of what happens with Remove Snapshot?

[wolftune]

I've searched around but feel unsure still. I'd like to understand what happens if I remove snapshots 2, 4, and 6 from a list of snapshots 1 through 7. Somehow, all the links and whatever are readjusted fully so that each snapshot is guaranteed to be as if it really were done over the remaining next-older one? And I still have an effectively complete backup if I do that sort of removal and then make a new snapshot?
