Turbine trainer tail config?

I’ve noticed that on the Pilatus PC-21 & PC-6/7, as well as the Super Tucano’s, the vertical stabilizers seem to be well forward of the horizontal stabilizer. Is there a particular reason for that? I thought I’d read what the advantage was but I can’t seem to locate the material.

The PC-21 looks like an absolutely awesome aircraft. 1600shp with an aerobatic weight of 3,100kg puts it in the class of the top WW2 fighter planes.
