The sandals found ant Fort Rock are 9-13,000 years old. The article refers to a 6,200 year old find.
He's right by the way. Presumably he's downvoted because people only read the headline and assumed the sandals are the same age as the baskets? TFA clearly states that the sandals "could" be as old as 6,200 years. Second sentence.

If you were aware of the Fort Rock sandals and their age, then this is not only possible, but quite probable given similar finds from thousands of years before already existed - on another continent.
