Not sure exactly what this meant: top water it?! what I do is soak it on a water for 30 mins then let it dry outside.
But if it involves bringing the plant indoors, which is implied by "then let it dry outdoors," it's probably not best. That would mean you would be constantly moving it back and forth between in and out.
It is a TREE! Think about how trees grow and then provide as much of that as you can. Put it somewhere and leave it there as long as it is happy there.
And yes if the chopstick is damp, that means the soil is damp, so don't water. If the chopstick is dry, then the soil is dry, so water. The other way around wouldn't make any sense.
If you just think in a common sense way about what trees need, you will be fine!
