I've got the multi and you need to drop the saddle mid-way (or just not to the bottom), let go of the remote lever and then let it spring back up and it just slots into the 1 inch drop position.
I find the 1 inch drop good for singletrack stuff and save the highest setting for road and climbs. May as well go for the 4 inch overall drop as the whole idea is that the saddle is out of the way – you ain't going to be sat pedalling with it dropped anyway, so get it right out of the way.
