`highlight-nonselected-windows' = t controls whether the region remains
highlighted in nonselected windows.

But after a command the region is deactivated, so depending on your
recipe you will not notice the effect of the variable.  IOW, in your
recipe, your command `C-h v' deactivated the region in the original
buffer.

To see the effect of the variable: C-SPC M-f C-x C-o C-SPC M-f.
