Understanding of OIP3


I have a question about OIP3 of ADL5535.
Datasheet says that OIP3 is 45.5dBm at 190MHz and 380MHz. Is this indicated as the total power of two-tone ?
And the attached file shows my understanding.
Please find attached file, and let me know my understanding to be correct or not.

My concern is the power to be defined as total power or each power.

Best Regards,
