Combined rider's & mount's actions in mounted combat

[vale73]

A rider on a war trained horse is already engaged in a melee combat. Can he do as follows:
1st: As one of his free actions (as per usage of the riding skill) the rider makes her/his mount attack
2nd: as its full round action, the mount attacks with both of its hooves
3rd: as part of its full action, the mount makes a 5 feet step backward, momentarily disengaging itself and the rider from the combat
4th: as one of his move actions the rider takes a healing potion from his belt
5th: as a standard action, the rider drinks his healing potion, without receving any Attack of Opportunity, because of the 5' step backward of his/her mount.
Can the rider and her/his mount act this way, or must the rider initiate and complete all of her/his action (even the free ones) before (or after) the mount attacks?
Many thanks again!

Yep, all good.

The rider must have the ability to command his mount as a free action, otherwise it is a move action to command the mount to do anything.

If the rider *does* have the ability to command his mount as a free action, then what you propose is possible.
