I never asked, but I want to believe their internal representation of “1D6” is one-dice-six.
Sorta like reading “1 x 6” as “one _times_ six” instead of “one _time_ six”
Words are fun.
Don't they sound the same?
dies daɪz
dice daɪs
I can't see any reason to think that native speakers are changing their patterns much because of what non-native speakers do or understand.

Then there's the other die, as in die-cast. I think these are typically referred to as dies in the plural. I'm not sure if this terminology is still in use, it seems to have been replaced with mold.
Then the other other die, referring to the fragment of silicon inside an integrated circuit. I've seen dice used more commonly, but both forms are in active use.
It's one of those frustrating inconsistencies of the English language.
I think die is still used when referring to metal stamping equipment and similar, but casting equipment is usually referred to with mold.
