NAT for self-originated traffic

Good day.

Please help me to understand.
My goal is to access the gateway via the loopback interface.
To do this, I'm creating a HideNAT in loopback from any address on any interface.
There are no problems with physical interfaces, but the NAT doesn't work from the VTI IPsec. It originates the VPN address, not the loopback address.
Why can't I create a NAT on a logical VPN interface?

I suspect traffic going into the VTI will do so before NAT is applied.
Not sure how SecureXL works with loopback interfaces.
