It uses the correct xyz coordinates from the client, in which y is height. All official lua from the main behavior framework treat y as height, and all API functions the bot regard y as height also. MAHA switched the y/z values because I guess people have a hard time accepting y as height...it's not my personal favorite choice because it confuses users in exactly the way you've experienced, but addon developers are free to implement functionality however they choose.
