I don't mean to nitpick, Tom, but is this really your plan?

I get that! But seeing it in this engaging book made me think about how conventions work: if you know you're reading a romance, then you already know a lot about what he thinks of her because if he really hated her like she thinks he does then you wouldn't be reading a romance, if you see what I mean. So in fact the POV switch conveys only a certain amount of extra information, rather than giving the entire game away. (And I wouldn't even be jolted if the POV switched between chapters, allowing me to get the same information.) In reading a romance, you already know a fair amount about how things will work between hero and heroine; the thrill is in the journey. And while it didn't work great for me precisely because I'm so used to requiring limited POVs to shift only at scene/chapter breaks, I can see how it keeps things moving snappily.
