Query doesn't respect #any-of?

So I'm trying to debug queries for the Elixir language and in locals.scm there's a query with this fragment:

(identifier) @_identifier (#any-of? @_identifier "def" "defp" "defmacro" "defmacrop" "defguard" "defguardp" "defn" "defnp" "for")

And when matching with this code:

def foo2(a, b) do
  :ok
end

It matches def, foo2, a and b (all identifiers), but it should match only def!

Why is #any-of? ignored? I guess that predicates aren't handled by treesitter itself but I supposed that nvim-treesitter would filter out the results that don't match.

Here's it running:

And here's the result of :checkhealth nvim-treesitter:
