Additionally, was there anything specifically, maybe the way I worded something, that caused you to come to your first two assumptions?

Not really, the first two assumptions were made according to how "normal magic" works, and the last assumption seemed somewhat logical according to my knowledge of coordinates.

I guess a way you could explain it a bit better is just to say that <I> is literally a fourth coordinate, rather than some special property.
