Why yhe five days to implement?
Broden asked for an order from the appellate court. It said it will conditionally grant the order - if Johnson doesn't reverse himself in seven days. The way that plays out is the lower court rescinds the order, and Broden does NOT get the order he asked for - but so what, he doesn't need the order any more.
The calendar week is also a courtesy, so Johnson doesn't have to rush.
