Well this was just an idea of some sort, not how it should be done. I've asked many people that offer some kind of servicer why didn't they implement bitocoin as a payment and the most common answer was the price but the second one was the confirmation time and there must be something that can be done, like a separate blockchain designed for that purpose, to speed it up a little.
Yes, this is what merchants complained about bitcoin. They advertise bitcoin as another option for payment because it is fast, however, in recent times this is not the case. So some of them removed bitcoin as a payment option. Although, I still remain optimistic about the changes that will be implemented, the question still remain is when. When are we going to see it, so that issues with the confirmation time will be alleviated or fix.
