Generally speaking yes, the orchid growing on trees with moss will need more moisture than those with lichen growing on the trees.
Moss and lichen can clue you in on the type of environment the orchid is growing in.
Moss generally and typically do not like drying out much. The environments they grow and thrive in generally have plenty of moisture year round whether it is through rain, cloud, water from a river or stream, swamp water, or humidity.
Just in case nobody quite understands what moss are...
They are non-vascular plants. The way they obtain moisture from their environment is far different from how vascular plants do it. Water retention in moss is also different from how vascular plants retain water. You can do some research on moss on your free time, (a side note: it is not easy to come across a lot of solid information on moss), and hopefully there can be a better understanding of the biology of moss.
Lichens tend to be able to tolerate less moisture, they are essentially fungus with photosynthetic symbionts. Many are also seasonal growers. They do have a period of dormancy, much like the orchids they grow alongside with. Lichens generally tend to be able to tolerate longer dry spells much better than moss do.
I guess the best way to know the difference is to experience the different environments moss and lichen come from.
Try finding a moss forest and hike through it. Likewise, find a forest where the trees are covered in lichen and hike through it. You'll start noticing differences between the two environments.
