Those who know Me as the Lord of material manifestation and of the demigods, and also as the Lord of sacrifices — even at the time of death, with concentrated mind, they know Me.

Three aspects of Kṛṣṇa: adhi-bhūta (who presides over material elements), adhi-daiva (who presides over planetary deities/demigods), adhi-yajña (who presides over sacrifices, present in them as the Supersoul).

Result: even prayāṇa-kāle (time of death), yukta-cetasaḥ (with united/concentrated mind) viduḥ — they know Him. This connects with chapter 8 on the moment of death.
