The ref output is the minimal delay through the chip covering the input and output pad buffers. It will vary slightly with temperature and voltage.
There are no negative delays in that sort of chip. It's just a bunch of gates/buffers with a carefully calibrated delay. (For a negative delay, you would need something like a PLL.) If the delay from the M12+T might be negative, set the antenna cable delay to be a bit short and add on a constant in software. -- These are my opinions.
