I think that he was speculating that since popular porn sites are already using flash that there is no need to switch. Or that there is some unmentioned barrier to switching video formats that porn sites don't have the means or ways to overcome. Either way, his point is unclear and I agree; porn can switch to HTML5 <video> tags when/if there is sufficient browser support.
