As optimistic as we can all be, this will always be a realistic possibility. It was running fine sludged up, and cleaning doesn't cost much in materials. If it lasts a year or two, I'd say he got his time and money's worth out of it and hopefully will have a little put aside for a new/rebuilt motor. Or he'll just ditch the whole thing and look under the oil cap on the next used SUV.
Sure it was "running fine" but what we dont know is what exactly is going on in the cam bearings, rod and mains. How long has this engine been neglected for? I would have to say with that amount of sludge its been many a years. Most likely over 5 anyway. I would really like to see all the bearings when he ends up tearing engine all the way open. That would be very interesting to see. I have a 5.3L on the engine stand that had around 120k (according to salvage yard) when I opened it up and the cross hatch pattern on the cylinder walls looks new.
