I'm not so sure this study proves anything new, too. We always knew some Goths came from Scandinavia, that they mixed extensively with less mobile people in the regions they passed through during the age of migration, and that Gothic identity was (at least eventually) more tied to Arianism than to ancestry, so that when they became Catholic they stopped identifying as Gothic.
The real wild Gothic origin story is that the island of Gotland got overpopulated and they decided by lottery which 1/3 of them should leave.
What is Arianism?
A non-trinitarian Christian doctrine, considered heresy by all Christians following the Nicene creed and vice versa. No relation to Aryans.
So it was quite literally a flood of people.
If you believe the origin story from over 1000 years later (by a guy who had read Jordanes' story written merely 500 years later), sure.
What seems more accurate is that there were people near the Vistula River around year 1 who had cultural, linguistic, trade and - yes - genetic connection to people on the other side of the Baltic sea, and in the age of migration those people got moving, got into Arian Christianity and called themselves Goths. They did comparatively well in a time when most of Europe didn't, so they have plenty of descendants, many of them carrying ancestry we can trace back to people who lived in Scandinavia before year 1.
