i think it's partly to do with the watchers - as far as i know they don't actually talk to anyone and when el'jonson fought luther it was the watchers who recovered him, took him aboard the rock, and watched over him as he healed. clearly they havn't shared this little nugget with anyone but as they are even more secretive than the dark angels themselves then i couldn't even guess about their motives.

he's not in a weakened state though, for all intents and purposes he's a 100% fit and healthy primarch. and according to the codex he's not even in stasis: apparently he simply 'slumbers' awaiting the 'end times' battle before getting out of bed... the lazy git :)

the only thing i can think of that might explain this is maybe the emperor is keeping him asleep until he see's fit to wake him.
