Swamy,
Namaskaram.
Brahma sutra is written by Sage Veda Vyasar as an explanation / interpretation to Upanishads.
Sage Vyasar refuted several schools of thoughts / sampradayams in Brahma sutra. But he did not establish Narayanan as Brahmam (as he understood through Upanishads) in his Brahma sutra.
What is the reason for this?.
Did this paved the way to other Mahans / philosophers to provide explanation in support of their beliefs by providing different meaning (விளக்க உரை) for the same slokas of Brahma sutra.
Request to clarify.
