HP loss does not always equal physical damage.
Therefore, hp recover does not equal physical recovery.
For example - in a fight, you are frightened half to death by a dragon & it claws you, causing you to lose hp. In 4e, after 6 hours rest you are back at full hp. You can, however, still narrate the scars on your side & the damage to your armour if you so wish. It just won't have a mechanical effect.
So I'm not sure what you mean when you say there is no way to be actually injured.
I can't speak for Jeff, but what I interpret the "no injury" comment
to mean is that no matter how much pounding, slicing, crushing, or exhausting
punishment a PC takes, its nothing that a 6 hour nap won't fix.
For me, this is one element that turns 4E from a swords & sorcery
fantasy game into a supers fantasy game. PC's effectively only have
"stun points". Too much stun damage at once can still kill but anything
less than obliteration is shrugged off like a mild headache.
It really doesn't matter how you choose to describe the effects. The effects of damage don't have to be descibed like wounds at all.
You can say that a PC who is down to 1 hp after a fight is very winded and bruised, but after 5 minutes of catching his breath, he is ok to fight again.
While this mechanic is functional you end up with fluff that more closely resembles a combat with the X men than a group of fantasy adventurers.
