Shade xml file question, will same glazing merge or not?

I was using the HB+ window group component to create a window group, but before that I have two xml files. One xml file is for glazing and the second xml file is for glazing plus shade, when I use those two files to create radiance BSDF materials will the glazing part merge together? Does it mean I should always have separate files one just for glazing and another one just for shade?
For the shade state component, if I use a glazing plus shade xml file, will it affect later on shade states? By asking this question, I just want to make sure that when I am not doubling the glazing material in the radiance analysis.

Any help would be appreciated.
Best wishes.
