I was considering that, while a round is six seconds, everyone (including the horse) is taking their actions in the same six seconds.
If I didn't have time in six seconds to both take a full move and then stop and swing a sword 4 times, why would it make a difference if its the horse that's taking a full move before I stop and swing that sword 4 times? The time he spends moving, I spend sitting on his back. It isn't available to me to use after the movement is done.
Think of it this way: I have to Ready my action until the horse stops moving, then attack. Does that make any better sense of the time sequence, the way I see it?
And then the next person (and the next 5 people or whatever) in the initiative order each get to take a full round action in the next 6 seconds.
Does it make sense? Not necessarily?
Is it internally consistent? Yes.
Ride on.
