Liquid and Solid Snake's appearance being identical in appearance was established back in MGS1, so it is extremely unlikely both would be Kaz's clones. In the real-world, Miller's appearance was changed by Kojima/Shinkawa to match Liquid's appearance, so that the latter could disguise himself as the former without much effort (sunglasses and hair tied back) for the purposes of Codec screen portraits.
