Quoting%20commentary for Zevachim 199:12

ולאחותו מה ת"ל הרי שהלך לשחוט את פסחו ולמול את בנו ושמע שמת לו מת יכול יטמא אמרת לא יטמא יכול כשם שאין מטמא לאחותו כך אינו מטמא למת מצוה תלמוד לומר ולאחותו לאחותו לא יטמא אבל יטמא הוא למת מצוה

For his brother': [even] if he was [both] a High Priest and a nazirite, only for his brother he may not defile himself, but he must defile himself for an unattended corpse.' And for his sister': why is this stated? If he was on his way to slaughter his Passover-offering or to circumcise his son, and he learnt that a near relation of his had died, you might think that he may defile himself; hence you read, 'he shall not make himself unclean'. You might think that just as he may not defile himself for his sister, so he may not defile himself for an unattended corpse; therefore it states, 'and for his sister': he may not defile himself for his sister, but he m defile himself for an unattended corpse.
