As useful as a well when water floods everywhere, thus are all the Vedas to the brāhmaṇa who knows

The analogy: udapāna (well) is necessary in dry land, but sampluta-udake (when water abounds) it is redundant. The well is not destroyed, but loses function.

Thus sarveṣu vedeṣu (all the Vedas) for brāhmaṇasya (of one who knows Brahman) vijānataḥ (who truly knows). Direct knowledge (vijñāna) transcends indirect means (śruti).

This is not rejection of Veda but surpassing. The jñānī does not need promises of svarga because they already know reality.
