All hops which are added to the boil will contribute
some bitterness to the wort, so the breweries marketing department can take bittering hops to mean whatever they please
Traditionally it has been stated that hops boiled for the full duration of the boil will lose the majority of their flavour and aroma and when there was a limited choice of hops this was in part true.
But given the massive selection of hops that are available today a beer that was bittered solely with Fuggles for example would taste completely different to one bittered with Chinook, if neither beer was given a late hop addition.
It is the late hop additions though that dominate the hop flavour and aroma of beer, so a late addition of a strongly flavoured hop will dominate and in most cases mask the flavour of the "main" bittering hop(s).
The amounts and timing off late addition hops will massively alter the character of a finished beer due to many and various changes to the hop components during the boil.
This is why breweries are happy to tell you what types of hop they use, but you will rarely get the amounts and addition timings from them.
So to answers the original posters question, sorry mate, no idea :wha:
But remember the beauty of home brewing is that you can experiment and even if the finished beer isn't quite an exact copy of the commercial beer it might just be better :drink:
