think about it like this:

Block:
"I actually doing computation in the main file, but to try something, in this block, as an experiment, I will set the vars to a"
(like when you're guessing an ansatz to a diffgl.)

Module:
"I really compute something new, like in a class, and afterwards I ship the result outside."

thats why in the example above the var=a already happended for Block and "a-a" = 0 immediatenly but in the module case he computes "b-var" and when it gets out of the module he sees that var is actualla a so it's b-a.
Module is a protected sub nb so to speak, which exports an object to the actual nb you're in.

some years ago I constructed a 7-parametric family of polar plots, see pic, so I got infinite^7 pics to contribute.
