Of course -- Digits take a lot less space then letters. It's pretty much known. Take this for example:

(-- binary, 2 bytes in length --)
5 (5) = 0000 0101
A (65) = 0100 0001

Now... Which one do you think has the least data to support? Plus they have to mention that the latter binary is a string. More calculations to make... Funness.
