Does the Federal Agency permit double collection of short-time work benefits (KUG) and full closure insurance (BSV) ?

Short-time work compensation (KUG) is only available as a subsidiary social benefit under the Third Social Security Code. According to legal regulations, benefits or insurance contractual legal claims from a business closure insurance (BSV) are credited, i.e. deducted. This is now said to have changed temporarily by an order of the Federal Institute for Salaried Employees (BA). Really?
