For a same virtual address, does the secure EL1/0 and non-secure EL1/0 see the same physical address?

Hello.

From the ARMV8A TRM, there is only single TTBR0_EL1 and single TTRB1_EL1, and they all can be accessed by secure EL1/0 and non-secure EL1/0.

For a same virtual address, does the secure EL1/0 and non-secure EL1/0 see the same physical address? If the TTBR is the same for secure and non-secure EL1/0, then it seems they will see the same physical address. Is this right?
