Yes that is the same tweet referenced above. They accused him of multiple things such as "groping female devs", "trying to pour drinks down the throat" of a drunk girl who bit his face. He apologized for SIC "shitty, creepy" behavior, but he never explicitly apologized for groping & wasn't accused of groping anyone specifically. I don't see how any of that is inconsistent with the author saying above that he didn't grope anyone.
I was just responding to your statmeent that Noah didn’t ‘didn't directly reply’ to the groping allegations. As far as I can tell, he did, as you can see in the screenshot.
I don't use twitter and they have multiple UI for platform but AFAIK when you reply it usually says "replying to @...", which it didn't have in the screenshot or archive.
