# Detail about reactive simulatability framework

I'm trying to understand the framework of reactive simulatability using *"PfWa2_00AsyncModel"* from this publication which is a tech report behind the paper A model for Asynchronous Reactive Systems and its Applications to Secure Message Transmission by Pfitzmann and Waidner.

I'm troubled with the remark 2.7 on page 6. Can anybody comment, why the configuration $conf_{1s}$ is in $Conf^f(Sys_1)$ if the port $p$ is not a port of $M_1$?
