You're overcomplicating things.
1) Katarina and Urgot have no protection, and Urgot won't even resurrect with a 50% chance. Insurance in the first night is quite possible.
2) Protections are displayed identically. In cases involving both Nebo and Gumer, insurance is present. There is no indication of manipulation with space. Has there ever been a case where the Doctor protects the back or redirects? This is not typical of the Doctor's actions.
Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
