Maybe it's just that some of the first schematic design entry I used thirty years ago adopted that convention, so it appeared natural to me, as in the two mentioned examples.
I'm quite open to adopt good reasons (unless they're better than my own good reasons, of course).
Oh, and by the way, the building example came from a mental image of a store department, or an elevator panel:
4. Useless things
3. Men's apparel
2. Children clothes
1. Women's department
(looks like us men buy clothes very rarely)
Correct. Almost: left apart graphs, so calculus and math are languages apparently ordering things differently, and oops... these are the languages for which "order" makes sense
(Yes, this was intentional play: just to throw in some silly phylosophy)
Oh don't worry, we'll soon need to use BGAs for almost everything, so my preference for 1:1 in schematic and PCB layout is already obsolete
