The chapters which starred certain characters being released on said characters' birthdays might be a deliberate choice on Isayama's part, but the alternating A-V chapter titles is definitely a coincidence, considering that pattern only exists in the English translation of the chapters' names (the original kanji/romaji for the titles have nothing in common as far as I can tell).
