The punches landed cleanly, again its not a question of the punches landing. Its how he or his body acts on the knockdown. Lieing face down with your elbow tense and held vertical, ready to push yourself up? Really? You ever seen anyone get knocked down like that for several seconds? It takes effort to hold your elbow in that position, and when you are temporarily knocked down / unconcious you certainly don't have that kind of bodily control.
From what I know that was Folley's traditional reaction to getting caught with a good punch. So unless he was taking dives against Liston, Lavorante, Jones, Foster, I'd say this was a legit knockout for Ali. A lot of people questioned Folley's heart. He had all the other tools it seemed but when he was hit he would "fold". In this fight he was caught early but fought back hard with whatever he had left at that point of his career.

I just read an exclusive story from the Sports Illustrated archives about Liston-Folley. Zora was knocked down three times; twice in the second round and then after about twenty seconds of the third round he was counted out. Each knockdown he went face forward to the canvas. So this must have been the way his body reacted when he would get dropped by a hard shot. Putting all of this aside I admired Zora Folley as a boxer. He should have been given a title shot many years before he fought Ali. At least Ali had the decency to give all deserving contenders a chance at the title. RIP Zora Folley
