If I thumb a dive and the other person doesn't want to go, whatever, I'll see them later on the surface (and not dive in Malta).
The interesting thing about the Malta dive, is that Castillo had little-to-no reason to thumb the dive for himself. So, he would have had to "thumb the dive for her." And that presumes Castillo had enough information in the moment to know that Gauci, a Scuba-Instructor, was not competent to decide for herself whether she was safe to continue the dive.
In hindsight, sure, she made a lot of mistakes and signs by the time the story ENDS. But it's not fair to judge actions, based on knowledge the actor didn't have, and things which haven't happened yet.
However, going back to the beginning of the dive:
So, there are really only two points for Castillo to "thumb the dive for her" being (a) before the dive and (b) after that initial buoyancy issue.
I'm fairly certain an average instructor would not have thumbed the dive for someone else at this point. The reason being it's somewhat common for a student to experience an issue (like a buoyancy one), the instructor fixes it, verifies everything is fine, and then continues the dive.

However, going back to the beginning of the dive:
- 20 hours no sleep? As a night-owl, I'm often (but not always) fine. Visible signs of tiredness? If you're motivated, you can hide signs of being tired a short while. We don't know that she looked visibly unsafe.
- Buoyancy problems early in the dive? Not great, but lets say you feel like it's been fixed. She thinks she's ok to continue, and she's an experienced scuba-instructor.
- What about any body-language or communication underwater? They were wearing dry-suits, scuba-masks, regulators, etc. Good luck reading body-language. And communication is just hand signals.
- --- anything after this point is mostly irrelevant to thumbing that dive, because they have deco-obligations ---
