In that it created a circuit inside the shoggoth where it translates between hex and letters, sure, but this is not a straight lookup, it's not like a table, any more than that I know "FF " is 255. This is not stochastic pattern matching any more than my ability to look at a raw hex and see structures, ntfs File records and the like (yes, I'm weird, I've spent 15 years in forensics)- in the same way that you might know some French and have a good guess at a sentence if your English and Italian is fluent.
