I think it's a mechanism to enable the Administrator to keep the company dormant in administration but to furlough instead of making the employees redundant. In that way, they'd qualify for the retention scheme and £2,500 per month instead of jobseeker's allowance. That does make sense and is a logical position.
What makes no sense and is not logical is returning vast numbers of Q400s to the skies to fly routes that made losses. Flybe ran out of cash and ceased trading for a reason, after years of alternating between a marginal profit and a big loss.
