Phusion Passenger extends Nginx and turns it into an application server. An application server is a program that runs application code, so in this case it allows Nginx to run run Ruby/Python code. Likewise, the Apache version of Phusion Passenger turns Apache into an app server that can run Ruby/Python code.
The benefits are not lost. Phusion Passenger integrates into Nginx to give you the benefits of both. For example one of the tasks of Nginx is to buffer HTTP requests and responses in order to protect apps from slow HTTP connections. Phusion Passenger fully makes use of this Nginx feature and even extends it.
