Looks like this plan is calling the reserve gas "hold." I can't speak from a dispatcher's point of view, but I would imagine that on scheduled routes the operator knows how long the aircraft will spend in approach patterns waiting for other traffic, and would factor that into the planned trip fuel. And the reserve is basically meant to make up for delays anyway, with the regs stating you need enough gas to get to where you're going plus 30 min... not enough to get there, some to wait around doing eights, and also 30 min for emergency.
An amateur's answer probably isn't what you are looking for, but maybe it will spark the conversation! Also, try re-titling (if you can) since this thread is about fuel loading rather than a specific aircraft.
