A wing is stalled when further increases in angle of attack does not result in a further increase in coefficient of lift (and mostly even a decrease in coefficient of lift). (https://www.av8n.com/how/htm/vdamp.html#sec-stall-definition https://www.av8n.com/how/htm/vdamp.html#sec-stall-definition) That's not the case for a delta wing in the regime that the article talks about. Increasing the angle of attack still increases the coefficient of lift.
