The Hero Capsule

So, I've been reading through the Art of the Film by Mark Salisbury this past week and more (I read it very sparingly, because books like this are like my most favorite collectibles) Most of the time I'm just enjoying the interesting artwork. But sometimes you see little things in there that give away clues to the movie, and other times you think you see something, but you're not sure. Now what I saw on p.160, in the chapter Juggernaut, is a detailed black and white sketch of the room where they find the Engineer, with the capsules and the pilot chair in the middle of the room. At the center of the platform, the lower most capsule has the words "Hero Capsule" written across it, while the other capsules are broken and filled with scattered remains of dead Engineers, no words written along those. Does this maybe imply something about the role that the living Engineer had in the past among his fellow Engineers? That he played some sort of heroic role in their last stand? Maybe his actions where cruel but necessary? It could be just a pet name the designers of the effects department used for the capsule. I know this is a feeble basis to base any theories on, but I just thought it was interesting. Maybe if one of you insists, I'll try to upload the sketch for you.
