Pretty much the title. The feat Mounted blade allows a cleave-type effect on a successful ride by attack in that you can attack an enemy adjacent to the original target at a penalty. However, would this target still be subject to the bolstered damage via spirited charge?

PS, does the mighty charge class feature for cavaliers allow a free combat maneuver check against an individual affected by mounted blade in addition to the original target?
