I found the same sentence
"When printed the top left corner of this box must be in the exact center of this page."
in this test case:
https://github.com/w3c/csswg-test/blob/master/css21/page-box/first-page-selectors-001.xht
This test case has CSS
@page:first {
margin-top: 50%;
}
, so the box's top left corner's vertical position is the center of the page's height.
I guess the author intended to mean that margin-top should be 50% in at-page-rule-001 too.
