This implies a user can use other tools to draw an intertwine zone, but switching tools just leads to ending the editing mode — which also does not get telegraphed well enough, https://illustrator.uservoice.com/forums/601447-illustrator-desktop-bugs/suggestions/45845602-make-intertwine-edit-mode-telegraphed-better.

While the action this pseudo-tool performs is more or less the same, the difference is murky. Either change the cursor or make the mode more clear.
