Anyone know anything about disc brakes?

Changing stem and bars on my road bike to shorten the reach will probably mean I'll have to shorten the brake hoses too. I've read this epicbleedsolution guide and skimmed through the levers' technical manual (they're ST-R785) and I'm left with two questions:

• is there an obvious sign than my levers/calipers are using the "easy hose joint system" without opening everything up?
  
• if they are using that system I guess the guide mentioned above doesn't apply, so what do I do?
  
  

Sorry for the noob question... hydraulic disc brakes are so wonderful :)
