Four connector hoses to mixer tap

[ozmeroid2000]

Hi - just wondering if anyone can help me with a bit of a mystery. I've recently moved house and was looking under the sink to prepare plumbing in a dishwasher point when I noticed that I seem to have four connector hoses going to my mixer tap.
I've never seen anything like this before and can't find any references to it online. I've posted a photo here. Anyone have an idea what they are and why there are two more than usual...? (I can feel hot water coming in through the one on the far left, but the front metal one becomes warm soon afterward. Likewise there is definitely cold running through the far right hose and I can potentially feel the rear metal connector hose moving slightly when I turn the cold on and off. Could there be two hot and two cold? If so, why would that be? Any help very much appreciated...)

H&C supplies in the braided hoses (left and right), mixed supply to spray head coming back down between them and the pull-out hose to the spray head at the back centre.

Thanks newboy - not only have you solved the mystery, but you've also helped me discover that I own a tap with a pull-out spray head. Nice.
