I used to have a Model 1. I believe the logical answer for why Drive 0 was
at the beginning of the cable was do that it was the closest to the
computer, ant it would make it less confusing for novice computer users:
Closest drive gets the boot disk.
As for the drive with a resistor pack needing to be at the end of the
cable, I disagree. I had a two-disk system, and both drives were
identical. I know that, because when I first got the computer, I plugged
the drives in, turned them on, turned on the expansion box, and turned on
the computer, and they worked. I tried the drives the other way (switched
them on the cable), and they still worked.
I'm also sure that neither had the resistor pack, because when I got the
computer, it was supposed to have 4 drives. There was, however, another
Model 1 with an expansion box, but no drives. The person who was selling
the computers took drives 3 and 4 off of the one that I got, and put them
on the other one. My friend bought it, and the drives worked on it, too.

It would have been a lot simpler if the connectors had been fitted in the
opposite order so that drive 0 was at the end of the
cable. Then the
terminated drive always would have gone at the end of the cable, and
would always have been Drive 0. No idea why they didn't do this.
