Hmm, possibly; I guess that would be conceptually simpler but

Don't see why. If mxsboot wrote both files at once, there'd be the
same number of commands to generate them.
Well, you'd have to copy two files instead of one to say SD, and run the
mmcload command twice instead of once, but now I'm just being pedantic :).
While U-boot gets the first one correct (other than the bad block
marker), it doesn't write the 3 after it correctly.
So if the first one were ever corrupted, the boot would fail. It seems
like that would be worth fixing.
supports two firmware images to boot from. That's one of the reasons
why the output of mxsboot is so big, as it contains two images. It's
not clear to me if the bootloader supports switching between image in
any useful way.
From the limited understanding I have of it, no, the second image is
only loaded if the first one fails.
