No the reduction is only to support people to maintain status. This does not increase rollover XP so in case of vinnyc rollover will be 50 XP.
That is disappointing. In effect, FB are treating those who have flown AFKL a lot less well than those who have flown it less. It seems to me that the decent thing would be to treat all FB members equally rather than disadvantaging those who fly a lot and temporarily lower the level across the board for all purposes, whether it be maintaining, promotion the higher level or roll-over. That business of arbitrarily making allowances for some FB members but not others is hard to justify.
