Looking through Dido et Aeneas (see here) the first two sentenced are:
Aenēās, vir probus bonusque, post bellum Trōiānum Italiam petit. Vīta eius ardua est, nam in multīs terrīs errat neque patriam habet.
I bolded the part I'm wondering about. Why eius here instead of sua? I get this is constructed Latin, but my understanding is that suus, -a, -um is preferred for reflexive use cases. And that seems to be the case here.
