That's true, but noticing a phenomenon using an arbitrary base isn't necessarily meaningful. Such as how in base 10 the digits of numbers divisible by 3 or 9 sum up to a number divisible by 3 and 9. There is an underlying principle here, but the specific presentation is just an artifact of the base. This article does a poor job explaining what (or whether) there is some new principle at work here or if this pattern is just a specific presentation of using base 10.
