Maybe you are right, but I don't feel that is the spirit of that CSS formatting setting. Those widows and orphans are here in order to help the rendering looking prettier, and I don't think those huge unnecessary blank spaces are a pretty thing...
So I suppose the correct behaviour is my strict one... Nevertheless I'm no HTML/CSS expert at all, so you could be fully right and I fully wrong, even being a complete absurd standard in that case.

I think your interpretation of widows and orphans is is correct. What I suspect is happening is that Kobo is being a bit pessimistic when working out the the amount of space left on a page. Having the bottom part of a line missing from the screen would probably be considered worse than a little extra whitespace.
Your pictures make it hard to tell. The exact number of lines on a page is affected by the number paragraphs and how much space is between them. I suspect these have the top and bottom margin set to zero, but I can't be sure. Because of that, you can't simply count lines.
The other problem is where does the text area finish? If you bring up the bottom menu, the line drawn shows the absolute bottom of where the book text will be drawn. Without that displayed, you can't be sure exactly how much of the text area is not used. There are plenty of times when I look at the bottom of the page an think that one more line could fit, but when I bring up the bottom menu bar and look at the space left, it is probably not enough.
With all the discussion on widows and orphans, I have never been able to come up with a good test case. The font size and the line length and text all affects this. That makes it a hard to get something that lines up to show the results desired.
