Yeah I remember those. Where I grew up that style of ring pull was the dominant style.
One reason why that style was retired in many places was to reduce waste. When you had a ring pull tab that peeled off, most people threw that away separately. I remember seeing those tabs being thrown all over the place.
I’m not sure that’s their intended design. Old pull-tab cans actually had a ring for you to pull them off (similar to “easy open” soup cans of today)
I’d imagine that as the tab shrunk and changed from pull to a lever action, the “ring” was left as a vestigial design (as a form of skeuomorphism)

Also, the one with the hole requires less material for the same lever width.
