Delete all users from Custom audience before uploading new user set

Hi Team,

I am trying to delete all existing users from an existing custom audience 
(user list) before adding new set of users.

I am using below code:

using (var userListService =
                
(AdwordsUserListService)_adWordsUser.GetService(AdWordsService.v201809.AdwordsUserListService))
            {
                //set the partial Failure as true
                userListService.RequestHeader.partialFailure = true;

                var mutateMembersOperation = new MutateMembersOperation
                {
                    operand = new MutateMembersOperand
                    {
                        userListId = long.Parse(customAudienceId),
                        membersList = null,
                        removeAll = true
                    },
                    @operator = Operator.REMOVE
                };
                
                var mutateMembersResult = await 
userListService.mutateMembersAsync(
                    new MutateMembersOperation[]
                    {
                        mutateMembersOperation
                    });
            }

My question is: 
Do I need to wait for all existing users to be deleted from the existing 
custom audience (user list) before adding new set of users ?

Thanks,
Abhinav
