Sri PBA Swami's Sarartha Deepikai:
Arjuna saw the superhuman acts of Sri Krishna since His childhood. He heard about Krishna's greatness from maharishis. And he saw that Krishna was always performing acts for him. Therefore, he decided that rather than following the paths shown by Krishna, he should seek refuge in Krishna Himself. After he had already taken that path, Krishna is telling him to seek only Him.
Hence, Vangipuraththu Nambi would state that this shloka is of the anuvAda rUpam. That is, repeating what someone has already said.
