It's also not the only lie he's told and admitted to. See his claims about herd immunity, where the numbers kept going up, and when he was questioned on this, he outright said he just gave out numbers that he thought the public would accept at the time.
I don't know which interview you're talking about, but in any event you don't know what his motivation was for saying what he said when he said it. Perhaps he was wrong, perhaps he changed his mind, perhaps he was rationalizing on the fly, or perhaps he lied.
It's clear that what he and other scientists said about masks early in the pandemic certainly changed over time. I think science is like that.
