So, this is a great question to which I had no answer (not about almonds specifically, but I've heard similar claims for e.g. hummus). I still don't have any answer, but I believe the answer lies in the realm of "glycemic index is a complex measure that doesn't exactly match any simple model for what it would be". For instance, fructose has a pretty low glycemic index (about the same as kidney beans, actually), and it's literally sugar.

From wikipedia, "glycaemic index (GI) is a number associated with a particular type of food that indicates the food's effect on a person's blood glucose."

Because glucose is a sugar, you seem to be confusing it with fructose (another sugar, 5-carbon vs 6-carbon). The glycaemic index specifically looks at one specific sugar -> glucose. Sugars aren't intrinsically bad, but often times they are removed from their origins which contain other constituents that help our bodies digest them (all sugar, no pulp).

yea that's not true exactly because of what you say:
