There isn't a direct connection. Look for connections between the two people forming the comm and you'll always miss the interpretation. The very idea of symbol comms is that they don't spell out what is being done nor connect the people, plausible deniability is paramount.

The people who know the context of these would not find them confusing to interpret, they know the inside story and take their context from that. They know the history of the comms in place. And they're meant to be weird- some of the most outrageously stupid comms have been used for events of importance. Just another way of laughing at us.
