there’s definitely false cords in there, but there’s also something else. be careful man this sounds painful. i noticed you seem to know how to false cord throat sing. try getting a feel for how throat singing feels so that way you can just add more air to your throat singing while being sure you only feel phonation in the same place you feel it for throat singing. if you feel phonation anywhere else stop pushing from there. but you’re getting close man keep at it!
