Sure. Some candidates are extremely experienced in negotiation and know exactly how much they are worth. Those people should absolutely name numbers from the start to avoid having their time wasted. But those people also know who they are and know that they don't need to read advice about negotiation.

Most candidates have no idea what they're worth. Here's what I imagine is happening behind the scenes in your scenarios, assuming a normal candidate:

Scenario 1: Recruiter: Great news. The candidate was happy with the offer and I didn't even need to ask for permission to offer higher comp. It's always extra time and work when I have to ask for $x+$y+$z.

Scenario 2: Recruiter: Ha ha. This candidate has no idea what the market rate is. They must only be interviewing at crap companies. We'll offer the bottom of the pay band and they'll be overjoyed because it's 10% higher than they were asking for.

Scenario 3: Exactly the same as scenario 2, except there was a brief moment when the recruiter wondered if the candidate knew how much they could get.
