House didn't want to squander Victor on that little gunfight. Of course Victor was sent to make sure the Courier would be safe, but you also have to realize how much of a value Victor is to house. Being one of two Securitrons that can move their AI from one Securitron to another is something House values pretty high. He doesn't even know about Yes Man's existence, so Victor is his only unique Securitron. One that he wouldn't give up just to "save" the Courier from a bunch of thugs.
Well... but that's just the thing, though. Victor
can transmit his program to another Securitron, and if you witness his destruction on the trip to Vegas, there's even dialog with him on the subject when you meet him good-as-new at the strip. It wouldn't be any sort of significant sacrifice to lose Victor's body in that fight, as his consciousness would remain unharmed. And it's not like the fight was long odds, anyway... if you (as a player) possess any skill whatsoever, you'll mop up every time, without enlisting
any extra help. House didn't have much of a reason to fear for Victor's life in that fight.
I don't think it's as complicated as some people make it though, either. I always interpreted the situation as House keeping Victor out of the fight because he didn't have any reason to keep him
in it. As said, the fight isn't long odds, and it's not like you're in much real danger. And House doesn't give a damn about Goodsprings, so he's not going to take any risks for it, even negligible ones. To me, it was the first real indication of where House's interests lie and how he conducts his business.
And really, he has no real reason to go to any great lengths to keep you alive, either. You were never a part of his grand plan, and it was a one-in-a-million shot that you survived at all. Victor pulled you out of the dirt, made firsthand confirmation that you no longer had the chip, put you back into play as one more of House's many, many long-term gambits, and that was that. If you'd been stupid enough to remove yourself from the equation in the Ghost Town Gunfight, you'd have proven yourself not to be the kind of man that House needed, and he would've found someone else to recover the chip.
Edit: Ninja'd twice. As to what Victor
says about being taken offline... I'd guess he's programmed to let the cat have his tongue in situations like this. House likes to play his cards close to his chest, and Victor did sort of play mum about being House's bot at first. It wouldn't exactly endear him or his employer to you if he came right out and said "Yeah, the boss told me to let you handle this one on your own, guy." It seems logical to me that Victor was a). simply lying, or b). incapable of perceiving or telling the whole truth due to scrubbed logs or behavioral filters or somesuch.
