I think it is just a general clause to try cover themselves should the blockchain fork they want no responsibility for funds lost through a fork or network going wrong.  The actual wording for who can submit a coin is open ended:

"If you are a developer or official representative of cryptocurrency asset, you can add this asset to Livecoin."

So a non developer can submit the application and thus the last clause is invalid?

I feel it is more them saying if u submit a coin and it is not updated to  avoid security issues or forks and the exchange looses funds then you are responsible for not informing the exchange to update the code or providing the updated code with security patches applied as and when... they want to cover themselves listing any coins that are just going to be under developed and left potentially leaving security risks on their serveres running the exchanges etc...

Anyway I sent them in an application and got this as a reply:

Hello.
Unfortunately, this year we no longer accept new assets.

...so maybe try in the new year? or should we look around for other possible listings?
