Just a side note: there is no such directive; there is
if_modified_since one.

The basic question is: how did you test?

Hint: never trust browsers and various "http headers" plugins, in
many cache-related cases they show incorrect info. Looking what
happens on the wire (tcpdump, wireshark) or at least intercepting
traffic with debugging proxy (fiddler) is recommended.
