Does it make Knox's "void warranty" = 0x1
There are two events that will trigger the Knox flag to change from 0x0 to 0x1.
- Unsigned recovery (recovery.img) is flashed
- Unsigned kernel (boot.img) is flashed
It's not the actual custom rom that trips Knox when you get to flashing. It's the step before that, getting a custom recovery loaded in order to flash the rom itself.
This is also why the de-la-vega root method works, because it flashes a prerooted stock system image to your device without touching the two partitions that DO trip Knox of modified.
Lucky boy! When I did the root procedure on my Galaxy S4, I did not figure out that I was going to lost my warranty increasing the Knox counter... Infact almost any root procedure will do this. But, as I told you before, you are lucky because there is some new root-procedure that will not increase the Knox counter.

Hope I've helped you!
