In Abhaya Pradhana Saram- there are six components for Vibhishana sharanagati. Trijada also rendered sharanagati for her protection; can her sharanagati also be construed as one to be rendered for salvation?

Trijada performed sharanagati for protection and not for salvation.
Notes:
The components of Trijada sharanagati were perfect says Swami Desikan in Parikara Vibhaaga adhikaaram of Rahasyatrayasaaram. But she did not perform sharanagati for salvation.
