That's the main thing, yeah - that the primary riding position (on the hoods) is waaay more comfortable over any meaningful length of time than using flat bars. But the variation is important to. You can use the tops as flat bars if you're resting or climbing, you can use the bends at the top, you can use the drops themselves.
I don't know why you wouldn't have seen people in the drops though, I use them fairly often. Sometimes while riding into a headwind, but mainly for descents and pathetic sprint efforts
Of course, if the OP already has a road bike then they'll be able to weigh up the benefits for their own personal uses. I would have said that a relaxed cyclocross bike would be the best fit for what they've described, but it depends a lot on the specific type of trails. If it's just dirt then any road bike would probably be fine. If it's grass and a bit of gravel then a cyclocross bike would handle it better. If it's rocks and gravel as big as your fist then maybe flat bars would be justified. But above all the key thing is that you're comfortable.
