गोविन्द भाष्य (श्रील बलदेव विद्याभूषण - अचिन्त्यभेदाभेद वेदान्त ब्रह्मसूत्र भाष्य सटीक)

The office-holders stay for the duration of their terms in office.
Purport by Śrīla Baladeva Vidyābhūṣaṇa
We do not say that everyone who has perfect knowledge of the Supreme
Personality of Godhead at once attains liberation. However, their accumulated past
karma is all destroyed by their knowledge of the Lord, and their present actions
also bear no karmic result. When the term of life in their present body is
exhausted, then they will attain liberation. Because they hold posts in the
management of the universe, Brahmā and the other demigods do not become
liberated until their terms of office expire. This is so even though their past and
present karmic reactions are already destroyed.
When their terms of office expire, then they become liberated and enter the
supreme abode of the Lord. This should be understood. The demigod Indra and
the others like him that have relatively short terms of office go, at the end of their
terms, to the demigod Brahmā, whose term of office is much longer. When Brahmā
attains liberation they all attain liberation with him. The author of the sūtras will
describe this later in this book (4.3.10).
As for the demigods opposing the Lord's desires, they do this only in
conformance with His wish, and in order to assist the Lord's pastimes. These
demigods may appear to be materialists engaged in sense gratification, but that is
only a false show. In truth they are transcendentalists fixed in knowledge of the
Supreme Personality of Godhead. Therefore, when their terms of office expire,
they all attain liberation. Of this there is no doubt.
