What is the reason of using activeEditor instead of editor from useLexicalComposerContext?

I am building my own editor using some stuff from the playground and I see usages of activeEditor, which is set like this

editor.registerCommand(
  SELECTION_CHANGE_COMMAND,
  (_, newEditor) => {
    setActiveEditor(newEditor);
    return false;
  },
  COMMAND_PRIORITY_CRITICAL,
)

It's been used for commands like activeEditor.dispatchCommand(UNDO_COMMAND, undefined);

I tried using editor from const [editor] = useLexicalComposerContext(); and it works the same, so I'm wondering why would I use activeEditor? Would I stumble upon some issues in the future if I keep using the editor from the context?

You can have multiple editors on the same page, the use case for this on the playground is the comment plugin, where the comment entry is a different editor than the main document one, so you want to toggle the active editor with its plugins, etc.

That makes sense. Thank you!
