Interesting, because I like multiple assignment to get just the opposite effect (also after many years of assembly coding). Given that the more of my code I can see on the screen at once, the more I like it, I tend to try to use a more horizontal style. However, I try to avoid piling up too many assignments (3-4 max), and only when the RHS expressions are simple.

Also,

horizontally.

Another case is when a few local control variables are being setup for some following block of code. I like that they are grouped together to essentially say “setup state for the following code”.
