You can only receive 1 5* from invite. This means if A invited B and C, C gets a 5*, then that's it. Neither B nor C can pass any further 5*'s to A.

On the other hand, chains don't work. if A invited B who then invites C. C getting a 5* will get passed to B, but it will not then get passed to A. B must obtain a 5* from another method (transmigrations count) in order pass it to A.
