The other thread is about Apple.
This is about Steve Jobs the person.
The subject of the sentence, "Steve Jobs resigns as Apple CEO," is 'Steve Jobs', not 'Apple'. As he resigned due to heath reasons, his continuing health issues fall into that line and therefore fall perfectly into that thread.
"Steve Jobs resigns (due to cancer)."
"Oh, now he's thinner (due to cancer)."
"*UPDATE* Now dead (due to cancer)."
The Apple forum didn't think it necessary to start a new thread to post the exact same photo you did -- they posted it in the resignation thread.
