Simple and gets the job done. Some potential questions answered: Yes, it will degrade your axe for each block mined; Yes, it has a range limit (it will stop mining if you go too far away); I think it only allows one at a time (but not sure I remember about that one).

Only one woodcutting process is allowed per player. But the process can include more then one tree.
If you dig a node from second tree without holding sneak key, during woodcutting is active, the second tree is added to the processing queue. The nearest tree is cutted at the first.
