Article one describes Daoxuan's two careers, vinaya commentary and historical biography, as sharing a single concern with getting the record of correct practice right, and names his position inside the Tang translation bureau alongside Xuanzang only as background to that argument. It does not mention that Daoxuan went further: within his own historical writing, he wrote specifically about Xuanzang's life and his pilgrimage, turning the colleague he had edited and proofread translations alongside into a subject of his own biographical work.
That choice sits at the exact meeting point of Daoxuan's two projects. His technical career gave him direct, firsthand access to Xuanzang as a working translator rather than as a distant, already legendary figure; his historical project, the Xu Gaoseng Zhuan, then gave him a form in which to record what he had witnessed. Working from his base at Mount Zhongnan near the Tang capital Chang'an, Daoxuan was positioned as few others were to write of Xuanzang from direct observation rather than from reputation alone.
The resulting account is one entry among the several hundred lives his history collects, but it is distinguished by that proximity: a vinaya scholar's biography of the celebrated pilgrim-translator he had personally worked beside, rather than a later historian's reconstruction from secondhand report.
