Does order matter when mixing acid (aqua regia)

Everything I have read says that when mixing aqua regia, one must add Nitric acid to Hydrochloric acid and not the other way around. Why is this? If one were to mix it backwards would it have different properties? I know acid poured into water as a safety precaution, is there a similar rationale behind the combination of two acids?
