I do believe the one exception to this rule is a Dwarf who also has the 'Cleave Through' feat, as that allows them to, as a free action when making a cleave maneuver, to take a five foot step if the initial hit, hits. Now then, if you've greater cleaving finish, and that feat also, would it be possible to 'chain' that, since Greater Cleaving finish creates a new cleave target if one of your targets falls, as in, you get to start a new single attack cleave.
