But that's the point.

What point, topposter.
Not only do you not have a point you allowed babblemouth another opportunity to add to the confusion once again.

While the device might incorporate a terminator, that doesn't make
it a terminated device. If the terminator is enabled then it becomes
a device plus a terminator - exactly the same as a device with a pass-
through connection and a terminator plugged into the end of the chain.

It's a fine distinction, but unless you make it clear then you will make
the mistakes apparent in your comments, confusing what a device does
in terms of line impedance etc with what a terminator does.

They are different things and they have different effects.

And since you didn't explain what the difference is no point was made.

SCSI is complicated today. U2W cables are actively terminated. Older
standards allow terminated devices (i.e. devices with internal
termion) as well as external terminators.

As it turns out UDMA capable devices has some sort of half-assed
device terminaton, i.e. _every_ device on the bus has some pull-up
or pull-down resistirs. Quite inelegant IMO.
