3.410

忘得曰離，涅槃從此而顯；有得曰著，名相從此而生。無名者，猶云無得。對前避文，亦可由離故得無名之理。

Forgetting attainment is called "departure," and nirvāṇa is revealed through this; possessing attainment is called "attachment," and names and marks are produced through this. "No name" is like saying no attainment. In contrast to the preceding phrasing to avoid repetition, it can also mean that through departure one attains the principle of no name.
