Also, self-checkout itself is faster here anyway. We don't have baggers, so in the cashier lanes you have to unload onto the conveyor and put your items into the bags yourself, with some awkward maneuvering since the register is between the conveyor and the bagging area. In self-checkout unloading and bagging is combined into one action: Lift item from cart, pass over scanner on the way to the bags, place in bag, and pay at the end without even having to move. No real additional work on the customer's part.
Also like the other response, I hadn't heard of explicit limits either, as long as everything fits on the bagging scale.
I think self check-out is only faster if you compare it to really, really slow checkout clerks with no dedicated bagger. I've been in grocery stores with fantastic checkout staff where 100 items were checked out and bagged in a minute and a half. Ain't no way I'm going to achieve that rate standing by myself there over a tiny kiosk where I need to find a bag, put every item into bags before scanning the next one.
They don't make a race of it, but I think they go at a reasonable "marathon" pace. There are also dedicated baggers. I should note that cashiers also accommodate other services like paying utility bills, or making withdrawals from one's checking account.
It's not just about speed, though, it's particularly about the unified lane and the fact that 2 self-checkout stations easily fit in the space of a single human cashier station (that may be unoccupied because of a store's hiring budget). It's also about peoples' patience. If a store hires less cashiers and enough people are still willing to wait in line such that there's profit, well...
