He is not suggesting that the self view has been eliminated completely before attaining jhana. If you read the whole sutta it is clear that those outside the Sasana - who haven’t heard the Dhamma may misconstrue their genuine deep meditative attainments in a variety of ways, all springing out of self view.
And of course even within the Sasana there can be those who misunderstand the Dhamma and who hold to wrong view at the pariyatti level . If they hold to these views, even if they are skilled in jhana they see it is evidence of self.
However the one who has understood clearly anatta at the pariyatti level is much less likely to go wrong.
