I wouldn't be surprised it's because the studios think it's probably boring to name the next couple of seasons with numbers, so they give them goofy subtitles. Then there's the ones who get carried away and just add punctuation marks:
S1: Seitokai Yakuindomo
S2: Seitokai Yauindomo*
S1: Oreimo
S2: Oreimo.
S1: Working
S2: Working'
S1: Seitokai Yakuindomo
S2: Seitokai Yauindomo*
S1: Oreimo
S2: Oreimo.
S1: Working
S2: Working'
