Right city, 2 of three rivers, but the Susquehana is farther east and flows through New York and eastern Pennsylvania to the Chesapeake Bay while the Ohio meanders west and south to join the Mississippi. I never really thought about it growing up, but having two rivers firm a third isn't very common.
I'll say it's plenty close enough as the Allegheny River is easy to look up when you know the rest.
So ask away.
