Minor typos (especially in the first sentence of the article) are a signal that the author and editors did not put sufficient effort into quality control. This calls into question the correctness of some of their deeper statements.
Typos do happen, especially if you’re writing in a foreign language. And occasionally, they even pass through quality control. If you’re questioning the validity of deeper statements based on two numbers being swapped (numbers that don’t have any deeper meaning in the context of the article) that sounds arbitrary to me.
But if it helps, the typo appears to be fixed now.
