It's clear Apple define "Hardware" as "Not using the main CPU". They've pretty much admitted it's firmware based, otherwise the T2 chip simply wouldn't be involved to be mentioned.

The T2 chip is mentioned in the quoted passage as an indicator of the architecture version, not necessarily an indicator that the T2 chip is directly involved

It is implemented in dedicated small CPLD that cannot be flashed by any software means. My understanding of relation to T2/SEP is that this CPLD serves as a kind of "IO expander" for T2/SEP which also hardwires logic like this.
