Don't want it to sound harsh but he's 94 years old. Could it be he just doesn't want to go out with a loss and is fine with his final score not fluctuating too

Don't want it to sound harsh but he's 94 years old. Could it be he just doesn't want to go out with a loss and is fine with his final score not fluctuating too much? Even if the markets don't correct/crash like his reserves seems to indicate, nobody can blame him for eventually being too early or not losing money opposed to gaining even more. Because this strategy seems to be in line with what we've been reading ("buffet amassing cash") for the last 5 years at least?
