Bryan was already at a depth of around 35-40 meters because he was done diving and preparing to ascend
Might mean he went deeper than 35-40m, especially with the deco stop talk, but as the article also said standard operating procedure was to "release his balloon to go up" it's probably just phrasing, and a safety stop.
Fingers crossed he drifted somewhere remote and is happily chewing betel nuts. That'd be a nice ending.
