Wording in mypy.plugin.Plugin.get_method[_signature]_hook docstring

Documentation

The docstring of these plugin hook methods currently say:

mypy/mypy/plugin.py

Lines 647 to 648 in 057508b

	class instantiation). This function is called with the method full name using
	the class where it was _defined_. For example, in this code:

...

mypy/mypy/plugin.py

Line 664 in 057508b

this method is called with '__main__.Base.method', and then with

I understand this to mean that the argument to fullname will be "__main__.Base.method", because __main__.Base defines method.

However, this doesn't seem to be the case. Setting up the same example in the docstring:

• mypy.ini

  [mypy]
  plugins = plugin.py
  files = test.py

• plugin.py

  from mypy.plugin import Plugin
  
  def plugin(version):
      return TestPlugin
  
  class TestPlugin(Plugin):
      def get_method_signature_hook(self, fullname):
          if fullname.startswith("test."):
              print(f"Hook will be called with `{fullname}`")

• test.py

  from typing import Any
  
  class Base:
      def method(self, arg: Any) -> Any: ...
  
  class Derived(Base): ...
  
  var: Derived
  var.method(42)

$ mypy
Hook will be called with `test.Derived.method`

I installed as far back as mypy 0.9x and it was the same behaviour as described above, displaying test.Derived.method (not test.Base.method).

Is there something wrong with the docstring (perhaps from outdated behaviour that no longer applies), or have I misunderstood something?
