Unknown L1-COM connection and 2 gang 2 way switch wiring (UK)

I'm trying to replace my 2 gang 2 way light switch with a smart one and getting completely lost in the current wiring and adapting it, I can't figure out why com would connect to L1 or find any examples of it online. Everything is COM-COM. Help identifying the current wiring would be extremely useful
