You seem to mean by this that you have a last level, the one
indexed by w.

I can drop the "informally": A tree with w levels! What is the problem

Nothing at all.
However, you have a huge problem if you are saying there
is a level that has index w.
It may make perfectly good sense, depending on your definition of
"tree".

Just one of the many problems this creates for you:
what is the index of the level immediately before level w?
Depending on your definition of "tree", it can happen that "level
immediately before" need not be defined.
Everything depends on the definitions.
Since we were not given any definition of anything,
what we can do, at best, is to guess...
Not very different to the way in which parents
may guess all sorts of meanings in their
newborn's guttural sounds. Except that our OP's
author is anything but cute.
