1-Wire Vcc GND - connect to Data GND on sensors?

-

hi,

i'm little confused.
the suggestion use 1 pair of cat cable data , data gnd
and pair vcc (5v) , gnd.

does mean on sensors connect them together?
if not think gnd vcc useless.
but on premade ds18b20 pass gnd through: http://www.fuchs-shop.com/download/manuals_for_t-sense_05-22-08.pdf

in attachment own sensor circuits - there can see better mean.

whom's suggestion? link?

it make sense though because cat 6 cable twisted pair-wise. having gnd on every pair makes transmission more robust, if connect both on both sides. btw, don't need 2 pairs, 1 enough if run devices in parasite mode.
