I don't blame you, the author miss uses the term short sellers in the beginning then uses it correctly later on. Which is confusing, initially they use the term to mean "any investor selling their shares of stock" which is annoying. Then later they use it correctly WRT a firm needing to buy the shares they sold back to give them back to the original lender, which I assume in this case is Charles Schwab. All in all, this article seems like a rough draft and needs to be proof read. I was REALLY critical and had to really focus to squeeze meaning out.
