I think that fits with how they think. HL3 has mythical status. We've already seen Valve devs make a major game in the HL universe and intentionally avoid "making HL3" due to this mythos. It takes a lot of confidence to say "Hey guys, I'm putting together the team to make Sistine Chapel 2."

(To be clear, I'm not saying it's a matter of ownership and personal brand. But someone needs to start the project and form a team around it. I don't think they're worried about personal brand, it's more an issue of reverence for the franchise.)
