Certainly not. The duties of the president of the USA are:
Execute/enforce the laws made by congress
Command the military
Grant pardons
Make treaties
Appoint ambassadors, judges, and officers
Report to congress about the state of the country
It’s not necessary that any one of those functions be the responsibility of a single person, nor is it necessary that any one of them be performed by the same person or group as any of the others. Some of these functions may not even need to exist as such; I don’t think pardons are a feature of all systems of justice, and a legislative branch has other ways to learn about the state of the country.
