a butt joint made with 1" Triton pocket hole

The wood is 15mm thick on the short side.

I did several test joints using thicker wood, e.g. 18mm and they
worked a treat.

But as the picture shows, on the thinner wood the screws stand proud
by about 1.5mm.

Errr, drill a deeper hole.

According to the instructions you raise/lower the jig's guide block to
match the thickness of wood being used

I'm not using that model, I'm using this:

But sure, the principle you describe would be applicable to any jig.
Trouble is, I've experimented with positioning the jig a little bit
forward or a little bit back, and the screw washer still stands proud.
The problem is really the washer.

It should work. 1/2" thick wood is supported after all. And my timber
is actually, at 15mm, a tad thicker. It might work if I could find
shorter screws, but Triton's only go down to 1".
