But considering that he is very smart at just 22 years of age (based on calculations from this year) I think that he might knew something at just 14 years of age don't you think? 
Maybe, but doesnt make sence he reveal his identity with altcoin development, when he could do the same with Bitcoin and stay in lead development of Bitcoin. For this alone I say not likely.
Although the not perfect (honed) programing skills Satoshi had might suggest inexperiened programmer at young age, but some senior experienced programmers have lower standards in code readibility / test methods at older age as well (its their nature).
