I interpreted that as they meant "amorphous solid" because they said it was not crystalline. But calling it a liquid if that's what they meant is a bit...wrong

  there is physics and there is language (and sometimes the twain shall meet). does normal glass flow at room temperature and typical earth gravity? nah. do glasses flow at some temperatures? who would deny it? so glasses are possessed of liquid properties. your non-crystalline statement is the properly important one (in my humble opinion), and it essentially defines what a glass is. and as a sibling commenter here states the thicker glass in panes in old buildings is probably a statistical phenomenon, or just possibly represents a glazer's choice, rather than anything to do with chemistry or physics or holders of phds, (by the bye, from experience, if a phd requires you to add a "Dr" to their name, that's a pretty good test of jerkhood (jerkship?))
