Yes, it did beat iTunes.
But, in all fairness, I take the number 1million not as a strict, accurate figure, but as a way to compare safari downloads to other browsers. If there were no other browsers, then there would be nothing amazing about 1 million downloads in such a short period of time. Its only stated to say that 'hey, look at me! I'm setting records here!'
1 million downloads gives the message: 'hey, I'm the bomb!', but I'm sure that all other download stats on other sites will use similar systems, and therefore the "safari tops 1mill downloads" headline is no different from any other "This program has this many downloads" news article.
