No, that's exactly what it is not. 'Sibling group' implies that there is no direct line of descent, but that at some point the tree of life forked, that Comb Jellies are in the one fork and that all the rest of the animals (including us) are in the other.

Not the parent, but some great-grandparent, yes.
