That page has mistakes in it like ''You almost never see scale leaves on a landscape plant'' and then goes on to say the immature leaves are a stress response. Not to put too fine a point on it, that's crap. I think he is also describing San Jose. The ''sage green'' colour is a bit of a give away.This link describes the three different type of foliage on Procumbens Junipers. I have a couple myself and they have mature foliage but go juvenal after any significant work.

Here is a good depiction of San Jose:
