The thing is, De Marco is clever enough to know that people are looking for symbolism in his tweets. He is either: 1. Doing it deliberately to wind people up (very very unlikely) 2. Ignorant of what people are looking for (impossible, given retweets and comments on his tweets) 3. Engaging in deliberate dropping of hints (anyone's guess) 4. Innocently posting (possible). Only he knows, but it is very very clever.
