Well you do have that guarantee -- as it is stated in the problem. It's clear that no matter what door you open, you will be shown a goat.
"and the host, who knows what’s behind the doors, opens another door [..] which has a goat."
The question is clear: The host (1) knows what is behind each door and (2) always shows a goat. It's clearly a determinate problem.
