Try the recipe after doing

    M-: (setq cursor-type '(bar . 1)) RET

Then you see that there are 2 characters in the scroll margin both to the
right and left.

OTOH, if you use the block cursor, you see the "odd result" you reported.
But I don't think the "visible difference" is a bug.

However, it may be argued that setting the margin to 1 gives a 2-char
margin is a bug -- however, then you really don't see any right margin
with the block cursor...

I really don't know how to "fix" this, so I suggest to leave it as is.
