Googling that with the brackets I get results containing "eggzackly this" ranked 3, 4, 6 (your comment) and 7 whereas the others contain just eggzackly (or with the 'this' preceded by punctuation as you mention).
Therefor I don't see how your last sentence is the explanation (there are results), I've also happened to land on no results found sometimes with overly precise quoted queries (for coding errors mostly IIRC). But it is annoying that it doesn't seem stricktly enforced even when you want it to.
