Ah gotcha. Yeah, for that I just had an implicit mental model of R1C1 without realizing it was physically implemented. I interpreted you (wrongly it seems) as saying that the relative offsets were confusing and I responded to that. You were curious about the implementation instead. I didn't care about the implementation when I was learning Excel, and simply assumed a mechanism like R1C1 without much interest in it.
