Vijay, would you mind looking into this? From a quick glance, I am myself not quite sure of the behavior when both clauses are present - I would lean towards checking for presence of both during semantics and generating an error. Also updating acc.loop verifier to not permit it. Unless you find a reasonable interpretation that would make both feasible.
