Commentary for Ketubot 167:4

אלא הלכה כרבן שמעון בן גמליאל דאמר אם מתה יירשנה ולאו מטעמיה דאילו רבן שמעון בן גמליאל סבר בדאורייתא תנאו בטל הא בדרבנן תנאו קיים ורב סבר אפילו בדרבנן תנאו בטל

Rather this is what was meant, “The halakhah is in agreement with R. Shimon b. Gamaliel” who said that “when she dies he inherits her,” but not “because of the reason he gave” for, whereas R. Shimon b. Gamaliel holds that a condition that is contrary to a biblical law is null but one that is contrary only to a rabbinic law is valid, whereas Rav holds that even a condition contrary to a rabbinic law is also null.
