In those cases, they are open ended, cut to match the roof pitch, and they dump out onto the roof. My dormer is pretty large, and i'm not even sure if it would be called a dormer, but i didn't know how else to describe it. The water is allowed to run on the roof surface and is collected by the lower gutters.

Instead, consider installing a downspout gutter, which will send the water from your dormer to a lower gutter. Generally, a contractor that drains a gutter onto a lower roof will say that it is an “industry standard,” whereas a contractor that rants against it will say that it's “not best building practice.” and both have good arguments to backup their opinion. These are almost always on dormers so they drain the water from that smaller roof down to the end of the gutter where it keeps on a movin' down the rooof to the main gutter system. It is very common for dormers and other roof structures that have gutters above the level of the gutters on lower portions of the roof, to empty onto the roof surface.
