But then why would the pilot hesitate to eject? They likely want to eject before they blackout, which is why I can imagine there could be a small chance to save the plane at human-intolerable g-forces.

They hesitate because in a fast moving emergency you can never be sure whether you have done everything or not. You have to decide in a split second. I also don't think a lot of problems are because of high g forces. Most problems are probably because of stall or other misjudgments.

Looks like there is a lot of chances they made a mistake then, and so an autopilot landing might actually work.
