Question about Reflective Shield

[herbal tea]

If two Disc Priest with reflective shield are having a duel. Both with shield on and one of them casted a damaging spell. Will that causes damage to bounce back and forth because of reflective shields?

[Sojourner]

No, Shadow Priest 1 (SP1) will reflect SP2's spell back to SP1, but it won't bounce off again. Basically, SP1 will deal damage to himself and SP2 wil hurt self as well.

Thanks for your answering. Though there seems to be some logic problem.
so the answer to this question is no .
