Cluster ssh and why is .csshrc moved to .csshrc.DISABLED

I find cssh very helpful, creating small clusters of 5 servers it’s very convenient and easy to track errors after running a command. I have set up an /etc/clusters file which works fine but before that I was using a .csshrc file. What I don’t understand is why every time I was using this file, it was being moved to .csshrc.DISABLED.

Moved $  HOME/.csshrc to $  HOME/.csshrc.DISABLED 

I googled and googled, and searched the man pages and every doc I could find, but I couldn’t find the answer to why this is happening. I am just very curious. Anyone knows the answer?
