When I got to the question about the soul I saw it as misleading and confidently selected the other option because previously the teleportation worked, and IIRC the other option had 30% success, both of which disproved the existence of a soul.
E.G: A family heirloom might travel between people on death and slightly affect the character of whoever's wearing it through self-perception, but (under the assumption that what I value is self-preservation) I wouldn't sacrifice my physical brain containing the only copy of my personality/memories/etc. in order to save it.
I'd guess what it's testing would then be whether you identify this thing with a pre-existing belief of an immaterial you, or already believe you are physical(ly instantiated patterns) and that this thing is just incidental - like any other environmental impact on yourself.
A version of this is what I took to be laid out by the 3rd question.
On this basis, the continuation of the soul is irrelevant with regards to the self. The death of the soul would be as immaterial to the self as the soul's continuation to "heaven" would be to consciousness.
