My understanding is the server needs to be configured explicitly to serve Expires headers for static content which is something that most WordPress users are unlikely to have done.  Or am I missing something or misunderstanding?

Bluehost uses servers configured to use ETags, and as such, this is
the behavior seen there (at no point are Expires headers even used):

On subsequent page load (no refresh): Static assets served from
browser cache, no server request made (just as Otto describes).
On soft refresh (F5, or clicking Reload): Server request made, but if
still cached, this will still result in 304.
On hard refresh (Ctrl-Reload): Full CSS file returned from server and
re-cached by browser.

At least, this is Chrome's behavior, other browsers may be different.
GoDaddy also uses ETags with the same behavior.
