I dunno, look at it this way...
Here's Berbatov against
Blackburn and
Everton last year:
Here's Ozil against
Australia and
Serbia.
Ozil's number 8, by the way. You can't see his number properly in the Australia game because the substitute Cacau occupied pretty much the same position, which is what I'm talking about really. Ozil played a clear line ahead of midfield, whether you want to call that attacking midfield or second striker is up to you, but they're both almost exactly the same distances away from goal and ahead of their midfield (if anything Berbatov's closer to our midfield and further from goal).
Also worth noting that their midfielders line up in similar positions, and again if anything it's Germany's midfield - and Schweinsteiger v Australia in particular - that is further forward. That's only because Australia got battered, though. Still it shows that they don't occupy different spaces even if the way they interpret the roles are different, I think.
Regardless over how we distinguish between formations we can see that positionally they're not that different, and that the difference between what we perceive to be 433 and 442 doesn't really matter because of how it's applied, in this case.
