SIP won't stay disabled - I think
The message you're getting confirms that you have SIP disabled as you can see that all the individual items are disabled.

The reason you're getting this sort of confusing message is that you've just re-installed El Capitan. It's the message format that was used in El Capitan 10.11.0 and 10.11.1. Apple changed this with the release of El Capitan 10.11.2 so that the message was clearer.
