forza italia?

i was trying to figure out what kind of scenario the group C of the euro 2004 will bring about.

BBC lists this as a explanation of the outcome of group C.

*If Italy fail to beat Bulgaria, Denmark and Sweden will advance to the quarter-finals.
*If Sweden do not lose to Denmark, Sweden will advance to the quarter-finals.
*If Italy win their game against Bulgaria the winner of Denmark-Sweden will join Italy in the quarter-finals.
*If Italy beat Bulgaria and Denmark-Sweden ends in 0-0 draw, Sweden and Italy will advance to the last eight.
*If Italy beat Bulgaria by two goals and Denmark-Sweden ends in 1-1 draw, Italy will join Sweden in the knock-out stages. However if Italy beat Bulgaria by just one goal and Denmark-Sweden ends in a 1-1 draw, Denmark will join Sweden in the quarter-finals.
*If Italy beat Bulgaria and Denmark-Sweden ends in 2-2 draw, Sweden and Denmark will advance to the quarter-finals.

*In the event of a tie, Uefa criteria will be used to separate the teams.

so technically, italy is screwed big time. they definately need to win, and to be very sure, they need to win by at least 3 goals. whoa. many might think since sweden thrashed bulgaria 5-0, this might be possible, but we've all seen what can happen. what i dont understand above the above is that even if italy wins and denmark and sweden draws 2-2, denmark and sweden still goes through. i think there's an error, coz im still trying to figure out what that means, but for all i know, so long as the goal difference is greater, that team goes through.

will we see the first major surprise of the tournament?
