To put it in slightly different terms: The AES key is only 16 or 32 bytes long (16 most likely). An RSA private key is much longer. The 16 bytes holding the AES key are super well protected against extraction, but this is expensive to produce on chip. The AES-encrypted private key is stored in less protected memory, but the data is useless without extracting the very well protected AES key.
