Well, your seed phrase already is secret.
Hiding a secret with a secret is like hiding the key of a safe in another safe whose key you hide in a third safe etc...
In the end one still needs the encrypted seed phrase and the key. Moving 1 out of 1 security to 2 out of 2 security increases security while decreasing safety. It's a linear correlation.
I'm not sure this is 2 out of 2, assuming you keep your seed phrases stored in different locations.
This method allows you to safely carry a copy digitally. So you can leave your steal plate in your home safe, but still access your corn if you need to.
