The Twitter thread claims that touch input/display, touch ID, secure enclave and camera are isolated on a separate ARM SoC. Since touch ID will be used for Apple Pay, and Apple Pay will be integrated into Safari, this architecture may be harder to attack from a malicious website that is trying to obtain Apple Pay credentials. Even if macOS on x86 is compromised, there is a separate input/output system on the ARM SoC for payment credentials.

Does the touch bar shows any info when using Apple Pay ?

In the Apple demo, the touch bar showed the recipient and dollar amount of payment, requiring a fingerprint to confirm.
