Life of an American Fireman?

I've been sitting here for an hour now, reading every comment on youtube and imdb.com, but still i don't know what to believe?!?!?!
Everyone's saying that 'life of an American fireman' wasn't the first film to use cross cutting, there saying that Martin Scorsese is wrong in the 'cutting edge' documentary we watched.

This video of 'life of an American fireman' isn't how it looks on the documentary we watched. in the Documentary they cut from the firemen traveling to the woman in the house, and say "you make the connection even though there in totally different places". But the youtube video above show something different?!?!??!?!?!?!?!?!?

Weather its right or wrong, i appreciate that cutting from one place to the next eg; firetruck to woman in a house full of smoke makes people put 2 & 2 together to make 35 and will take it on board when doing stuff my self.

This, on the other hand (below), by D.W Griffith called 'A Corner in Wheat' made in 1909 is a good example of Cross Cutting.
It tells a story of the rich and poor and cuts between them both in different places, but you get whats happening and it evokes an emotion, just by cutting between them both. If they were separate, then it would seem like two different stories.
