25.97

釋曰：無學心生時者，謂初無學心於未來正生時也。此正生時，從煩惱障正得解脫，名正解脫。若現在世名已解脫，非正解脫也。

Explanation: 'When the aśaikṣa mind arises' means the time when the first aśaikṣa mind is properly arising in the future [state]. When it is properly arising, it properly attains liberation from the obstacle of afflictions, which is called 'proper liberation'. If it were already in the present tense, it would be called 'already liberated', not 'properly liberating'.
