Nick the two line option from the calliper is the most common on race bikes as it only envolves banjo fittings, my 998 has a T- piece just above the bottom yoke but is not the way I would go if I was making up the hoses myself.
Some bikes do come with a splitter box that is usually cast alloy and is bolted to the bottom yoke, again this system usually only envolves banjo bolts but in this case 6 of them, the weak point of this system is that the splitter box can easily trap a bit of air that is hard to bleed out.

My preference is Two hoses from the mastercylinder fitted with a double banjo bolt that has a bleed nipple in the end, unless you use a Brembo or AP Master that has its own built in bleed nipple
