Indeed. However, note how small the sample size is, which makes it extremely difficult to draw conclusions. Quote from p14:

> Finally, we considered the possibility that seniority may be at play and that gender simply coincides with seniority. We recognized that two of the three female Justices, Justice Kagan and Justice Sotomayor, are more junior on the Court and that each is interrupted far more frequently than Justice Ginsburg. In addition, Table 1 provides some provisional support for the seniority hypothesis because of the most senior Justices - Ginsburg, Kennedy, Scalia, and Breyer — only Ginsburg and Breyer are interrupted at high rates. In contrast, the more junior Justices — Kagan, Sotomayor, and Alito — account for the other seven high interruption rates.
