Notice how the arrow clearly shows that you want to go OVER the polls (like G.W. Bush), and not through them (like Bernie). This applies for both completing your hunter/jumper test, and your piloting license test. If you crash into the poles with your flight school's Cessna, they will not be handing you a blue ribbon.
More pertinent diagram information:
I like how very clear this diagram is to show that you will be riding a horse through these standards, and not a Cessna 172 Skyhawk. Also, that the horse is supposed to jump over the poles: I've been to SO MANY horse shows where that instruction is not clear.
