How will the Syscoin-Ethereum bridge help Ethereum; how will it help Syscoin?

Is any developer planning on using it? I'm talking about this:

> The Syscoin <=> Ethereum bridge is a system that allows Sys and Sys assets to be moved from the Syscoin blockchain to the Ethereum blockchain and back.

Docs here, but I'm in over my head with them: https://github.com/syscoin/sysethereum-docs
