> Valeria Chomsky said via email that her 95-year-old husband is in a Sao Paulo hospital, where she took him on an ambulance jet with two nurses once he could more easily travel from the United States following the June 2023 stroke. The couple has had a residence there since 2015.

Seems that you're partially correct. The AP says he was taken on an ambulance jet, not a rental one (or perhaps it's a rental ambulance jet, I don't know).
They also say this happened "once he could more easily travel from the United States following the June 2023 stroke". It sounds to me that they've been wanting to go back to Brazil since then. This may be because they live there and were keen to go back home; it could be because he has his regular doctors there who may be able to provide him with a better treatment; it may be that they would have better support (from his wife's family, for instance)...
In any case, they live there so it stands to reason that they would want to be back as soon as it was feasible.
