There's a distinction between biologically modern and behaviorally modern humans. Biologically modern humans have been dated to at least as early as 300k years ago. However behavioral modernity, is more recent. There's debate about how exactly to define things and draw a line, but it's generally around 70k years ago.

The article isn't particularly well written but that's probably what they're referring to.

Might also just be talking about specific geographical range. There is still a lot of debate on the time line and nature of the diaspora of modern homo sapiens.
