Surely Windows keeps the FVEK in RAM regardless of whether the TPM requires a PIN to initially obtain it. Otherwise, wouldn't you need to enter your PIN every time a block from the disk needs decrypting? Not to mention the performance impact of calling the TPM on every disk operation.
This attack reads the key from RAM, so I don't see how a TPM PIN would mitigate it.
