Yeah, that is interesting. It mentions Orlando by name, and even though his death is supposedly similar to Sal's, the text is different so it's not just a name variable... so clearly you've programmed the conversation in somewhere, and it just wasn't supposed to actually be possible in the demo.
The dialogue you're viewing is just placeholder stuff so thankfully it's not spoilers for how his route goes down. I've isolated what the problem is and will be patching it sometime today. Essentially, the check to see if his content is there wasn't working. It's supposed to see nothing is there and then boot you back to the title screen, but... it's not doing it. Either way, it'll be fixed by the end of the day
