And while it's true that terminating and some repeating expansions in a
given base can have other representations (e.g., 0.999... = 1, 0.3759836
= 0.3759835999..., etc.), I'm pretty sure that all irrational expansions
in a given base are unique.
Since normality only concerns irrational numbers, the question of
non-unique expansions doesn't seem to come into play.
