I decided to take the plunge: I multiclassed into fighter.

Is multiclassing in, or do you think he's just referring to a selection of feats and abilities to mimic multiclassing?
Based on one of the Mearls comments in a podcast, my understanding is that multi-classing exists in two different ways in 4E: (1) You can take powers from other classes and (2) Proper "multi-classing" in which you gain some of the class abilities of the new class.
I note that #2 is important because, if you want the feel of a fighter, you need some of the "sticky" abilities that, from the DDXP character sheets, appear to be class abilities - not powers. However, unlike 3E, multi-classing does not appear to give you all the stuff that you get by just starting at level 1 in a class. Mike specifically noted that this was very constraining in 3E because you couldn't give a class all of its characteristic abilities at level 1 because that was too vulnerable to splashing.
This strongly suggests that there is some mechanism for slowing gaining class abilities over time. If all classes gain improved class abilities over time (like the Rogue's improving sneak attack), then they may also include a multiclass table which grants those abilities over time to a character that "multi-classes" into that class.
For example, maybe multi-classing into cleric lets you do one Healing Word per encounter. (Note that the power is labeled "Cleric Feature" suggesting that it is a class ability, not just a selected power.) Whereas, a full cleric starts with two Healing Words per encounter in which both the bonus hp that is added to the surge increases and the number of Words per encounter increase over time. Similarly, a fighter-rogue would have sticky (defender) class abilities from the fighter and sneak attack (striker) class abilities from the rogue. Maybe the multi-classed fighter has the ability to mark, but doesn't start with the extra-sticky abilities? Maybe the multi-classed rogue has only a 1d6 sneak attack and doesn't have some of the rogue training and other class abilities?
The idea that you give up some of your native class abilities to gain new class abilities is what makes this seem like a "plunge". It's quite different from forgo-ing the next warlord power to gain a wizard power. That's just an extra ranged attack, you're not compromising on your leader-ness.
But, of course, this is mostly speculation...
