I am not sure but you are maybe hitting bug 4389 which I have just 
recently filed:

The basic rule is that you also need to have a Cache-Control header in 
order to enforce somethings.
If you have a "must-revalidate" rule it would be reloaded.
Also from your logs it seems that you or the client have not tried to 
"refresh" the request using some Cache-Control headers or using the F5 
button(when in some cases it won't work).

Try to remove the override instructions and use 0 value for the min and 
see what happens.
