Unfortunately, this can happen, and there is no warning advising the CSA that removal of the only other Approver would result in transactions that could not be approved and therefore would never get executed. The transactions would continue to show as requiring approval; this would alert the CSA that there are outstanding approvals. To remedy the situation, the CSA could give another user Approval status, or create a new user with Approval status; otherwise the CSA would need to contact the bank or the Customer Contact Center for assistance.
