Yeah, its for gameplay purposes.
In sprite games they just mirrored the whole sprite.
But with 3d graphic 2d games they have to still mirror 'special' limbs
like k's hand cos its the one he uses to make the fire stuff.
Same like with vega's claw, it switches sides.
You'll notice sagat's eye patch stays on the correct side, whereas in the
2d games it also switched.
Also, thats why guile has an American flag tattoo on each arm, and deejay's
pants has the word 'maximum', because when mirrored, it looks the same.
