With visa requirements there are a lot of details involved, it's not as simple as nationality -> visa requirements mapping.
This is what industry professionals use to check if you are eligible to board a flight.
So yes, technically you need a job offer for O-1, but it's just a formality. Personally, I agree that it doesn't make much rational sense either, but then again barely anything makes sense when it comes to (US) immigration laws.
Can you give some examples of that actually happening? I'm a bit skeptical it's that easy.
