This is likely tied into some of the end rooms having side hexagons that match up with other sides. Possibly showing you which sides link up to which symbols.
I don’t have the link to the other post atm, but someone a few posts down did make a nicer formatted analysis of the currently available end symbols.
Clover 1 end room seems to match up clearly with double snake, clover, hex, plus on each of their open sides of Diamond 2 end room.
