It is unclear to me if the dealer is
going to completely replace the diff fluid.
Could you clarify please ?

It is one of the areas of the recall and procedure that is unclear.
The recall, as has past service information, talks about the importance of keeping the pinion bore free of fluid. Fluid that could give the perception of a repeat failure.
It does not require, or list it, it as one of the steps in performing the seal replacement. The parts information lists the required fluid and additive, but the payment section makes no reference to it.
But, it does go a one step beyond though and states "It may be necessary to drain some or all of the axle fluid...".
It would appear it is up to the dealership or their tech, on what to do.
With out further guidence from GM, or dealerships getting claims bounced for excessive parts allowances,
my recommendation would be to request that the procedure be done with a full drain and refill. Also request that they read the latest service procedures in the electronic version of the service manual, use all the proper special service tools, lift it carefully, and use the additive if required.
