It certainly wasn't good D&D, though it sounded like they were at least having fun(the most important thing.)
The players weren't familiar with the rules and the DM was a stranger, so the game progressed kind of klunky. It's a credit to the DM that he kept the pace going as well as he did. There wasn't much roleplaying going on other then the guys joking and cutting up. The DM didn't really give them much flavor and background to play off of though(other than a NPC goblin named Plug.) This was understandable given what that session was trying to accomplish, though.
I'd put up with that kind of game from a new group for a few sessions, but if the campaign didn't progress into something with more depth I'd probably drop it and move on.
Under the circumstances just about any FRPG would play like that podcast, D&D or not. That podcast doesn't back up your argument very well(and why do you need it to? 4e says D&D on the cover. Case closed.)

All the things that you point as missing (see bolded parts) are not parts that are unique to D&D. Even with this elements, any FRPG would be the same.
These are really not the specialties of D&D. These are the features of any role-playing game.
It is all a matter of association. People that play lots of D&D associate the type of games they play with D&D. The games I play in have a lot of joking going on between players. Hence, the podcast sounded to me like a very typical role-playing game session. The things that made it typical D&D was that they were playing the typical D&D character archetypes against typical D&D monsters (Goblins and Undead - of course, these are not unique to D&D, but they are typical for D&D.)
The dice they rolled (they mentioned them a few times, because at least one of them didn't have his own dice) might have made it more typical D&D. (In Warhammer, they'd have only rolled d10s and d%.)
But - Dice, Classes, Monsters? Is that the "heart" of D&D? Sounds a little to pedestrian for that?
But can it be role-playing a lot or the DM giving flavor and background? I mean, that sounds really important to a game high on the "More Refined Than Mere Hack & Slash"-scale. But is that the "heart" of D&D, if it is something that you would want in any other RPG, be it D&D, Warhammer, Torg, Starwars d6, Starwars Saga Edition, Savage Worlds, Call of Cthulhu, Shadowrun, Rolemaster, Exalted or Changeling: The Lost or any World of Darkness game?

So, what was the original topic again?
Maybe different versions just have different goals, and that's okay.
They have different goals in some areas. But don't let that fool you to believe that not every edition wanted to be a role-playing game.
The different goals are found on a different level of detail. And I suspect that the goals are often very similar, but the weighting of the differing goals changed.
