When running prewired parallel cables does the ground wire need to be sized per the largest ampacity that you are trying to acheive?

Also if parallel grounds are prewired within the cables do they pair up to handle larger amacities?
 
250.122
(F) Conductors in Parallel. Where conductors are run in parallel in multiple raceways or cables as permitted in 310.4, the equipment grounding conductors, where used, shall be run in parallel in each raceway or cable.
Each parallel equipment grounding conductor shall be sized on the basis of the ampere rating of the overcurrent device protecting the circuit conductors in the raceway or cable in accordance with Table 250.122.
 
In order to meet 250.122, most wire manufacturers do offer MC cables with oversized equipment grounds (often special order--but available)
