For a future travel voucher is issued for an avios reward booking if the new avios booking with the voucher is less avios or cash then the difference is refunded to the customer. See this reply in the rebooking thread (you may also want to review some of the posts in that thread):

This is different than for vouchers issued for cash bookings.
