Mmm.....maybe. Still, my experience with power LEDs is that they simply don't die unless the power supply goes bad or they are given pretty severe mechanical shock, and in this case it would nerf all the other LEDs. I don't think redundancy is the issue here.
Maybe it has something to do with power. Bunches of LEDs would allow for a much higher forward voltage and smaller total current loads. That makes for a simplier and less complex driver, but would require the expense of more LEDs, which obviously aren't an issue because it's nit like Philips is buying Crees.
Curious if PhotonWranger can make any sense of this with the bulb open. Anyway to determine how the arrays of LEDs are wired; number in series, etc.
