The article, and possibly the author of the code, incorrectly define Fully Homomorphic Encryption. FHE doesn't have much to do with obfuscation. Formally, its the task of making the ciphertext malleable so that you can perform addition and multiplication on it such that these operations are translated over to the plaintext as well, thus allowing servers to operate on encrypted data without knowing what they're operating on. The techniques used in FHE have been applied to obtain Indistinguishability Obfuscation, but that's not the intuitive notion of obfuscation, and the intuitive black box obfuscation for general functions was proven to be impossible over a decade ago.
