Spicy, as in "using chili peppers," meaning it has capsaicin gives a bit of a lie to this. You literally just add capsaicin to food to make it spicy in many places. Is how they can give a number score to how spicy to make it. Leaving out the capsaicin does not change the base flavor profile at all.

Now, it is confusing, as spiced food is typically not spiced with capsaicin. Rather, spiced food has traditional spices and is often not spicy. (Think spiced rum. Not "hot" at all.)
