As far as I know, yes, and UPI/"FedNow"/Cashapp-and-friends don't change that. That being so, if I'm honest I'm not really sure where the prior commenter's objection originates. Maybe they know about some directly accessible clearinghouse that I don't? I'd be surprised for several reasons to learn such a thing exists, but I've been surprised plenty of times before.
Unless this is actually possible in some country, I think they're both confused. But I'm guessing the objection was probably intended to convey "this is just as 'direct' in the US as it is in Australia", which would seem like a valid objection to the article.
In the article author's defense, he did pretty much disclaim any detailed or experiential knowledge right up front. That said, while my own relevant experience is now many years past and was in any case mostly refracted through the payment card industry, I didn't spot any obvious howlers.
