I should have said:

[
An abs. pos. non-replaced element's border box (which is the area
painted by background-color of the element and the borders) will be
vertically centered within its containing block only if both
'margin-top' and 'margin-bottom' have equal values and if 'top' and
'bottom' have equal
values.
]

because the border-top-width and border-bottom-width could be asymetrical.
