Basically, yes. If the horse is going to move away from something, you want the horse to still be facing it. For instance, you could approach the horse from the front and to the left with the hose, and have a lead on the horse, and as the horse backs away, you just calmly follow. You don't even have to spray water. Sometimes it's better to take things in stages. Let the horse get used to the hose itself, then the hose being on, then the water being on the horse. You follow until the horse stops moving, then remove the pressure, back away.
The second method of doing this, is to have the horse follow the hose. Have someone else walk ahead while dragging the hose, and you follow after with the horse. This can help them realize that the big scary thing is actually running away from them. Don't be surprised if the horse wants to catch up to it and sniff it or chew on it after a while. :)
