That's correct. O-rings did not eliminate the need to lube a chain. They just sealed in lube where it is harder to get to. The bonus is that you don't have to drench the chain with a heavy, sticky lube anymore (which also helps keep it clean).
I shoot a bit of silicone/teflon lube (which doesn't attract much dirt) every few weeks and it works for me. My last 3 o-ring chains made it to the mid 20K mi. range. Optimally, you want to direct the lube onto the right and left edge of the rollers for proper coverage of the spots that don't have sealed lubrication.
