It's about being allowed to stake some claim to that legacy and that story, as opposed to having your own definition of yourself smacked down / taken away, and that's an even more pressing concern for Robin, who we know is driven by that consciousness of the past. I think that Nikki's coat is mainly important as a symbol of who's really going to be allowed to help define the issue. Characters of color: nuh-uh. Spike gets the last word in all his face-offs, figuratively (via coat) and/or literally. As the final voice of white authority, Buffy reinforces it vis-à-vis Robin.
As for a Wesley/Robin parallel, it's certainly there. However, I think it serves as a good critique of the dangers of allying yourself with the Great White Patriarchy - if Robin's alliance with Giles is a silent one in the vid, Dana's story makes it clear that those Watchers are as likely to shoot you up and shut you down as support you, depending on their own interests, if you're acting against the GWP. Really, I see either Angel (as the head W&H honcho) or Wesley as more analogous to Buffy in the Dana vs. Spike / Robin vs. Spike episodes, given that Wesley strikes the final blow in shooting down Dana, and Buffy's words to Robin are the final blow after Spike taunts and beats the crap out of him. Robin's already losing to Spike when Buffy arrives to rescue Spike / tell Robin off; Dana's succeeded in cutting off Spike's hands when Angel and Wesley arrive to rescue Spike. But the two episodes end the same way: Spike wins in that he gets to sets the final terms of how we think about their stories. The Robin POV reframes things so it's as if Robin looks to the past and sees Slayers who are women of color, defeated by Spike; looks to the present and sees Slayers who either collude with Spike or fall victim to that collusion / white patriarchy; looks to the future in Dana, who has access to all Slayer experience, and still sees defeat all over again. Robin himself has failed - or rather, the Buffyverse narrative has failed him. Robin's position allows him a unique perspective on the persistent racial failures of the Buffyverse and the stories it tells.
