Because exploding the tank on his back (which is hittable from the front too) will momentarily make him unable to shoot the flamethrower, and during that time you can take out the tank on his left leg. There isn't usually quite enough time to take out the leg tank, but you can quickly shoot the pouch and that will cause him to flutter for a bit.
The pouch is necessary to take out if you are keeping him at a distance, because he fire bombs you and it is quite damaging. Take out the pouch and he no longer has a medium to far range attack.
