Can someone explain how "I have my whole genome sequenced by Nebula" relates to the news just now that "The human Y chromosome has been completely sequenced"?

How can someone have their whole (!) genome sequenced already when so far we weren't able to fully sequence the Y chromosome. And this person seems to have a Y chromosome.

because commercial "whole" genome sequences aren't really whole. But, they normally deliver the raw reads to you in a 50+GB file so I suppose you could take the reads in that file that don't map to the previous reference and try to map them to the new one. Unless you are an expert it's unlikely you would get any actionable results.
