The problem isn't the repetitions in themselves...
There are many examples of repetition in old manuscripts and many more that would result from certain methods of encoding the text.
One of the enigmas of the Voynich manuscript is that many plausible explanations for the repetition (particularly those related to encipherment) carry a "price" in terms of reducing the "working set" of characters or words within the manuscript to a number that appears inadequate for expressing most known natural languages.
