Watch the scene closely - he's struggling to fight it and it just swats him away (it actually breaks his weapon when he becomes DRG!). And, remembering back to the level 70 SCH Job quest and Lost City of Amdapor HM, what elemental alignment did the Amdapori specialise in (and which their constructs like Kiburu were powered by)? Light. And what is Light's elemental opposite? Darkness.
So it made sense in a logical way - he bcame DRK simply for pragmatic reasons, reasons which I'm sure will be given greater clarification and context by the complete trailer next year just prior to Shadowbringers's launch date.
