Bitterness is still extracted but at a lower ratio, depending on the gravity etc. There would be a few IBU from the 30 minute addition, but no where near the same as if it were a 60 minute addition. If you do the calculations, it would work out around 13-17 IBU depending on a few factors just for the 30 minute addition.
The timing isnt strict at 0-15 for aroma 20-40 for flavour and 45-90 for bitterness, "flavour" consists of bitterness and aroma.. the shorter the addition is in contact with the boiling wort, the less bitterness in the final product, which is why you have to add **** loads of hops late to get any IBU.. An example would be a 10 minute IPA etc.
