As long as there isn't any detail about what they meant with these, you can expect everything from a developers team which officially ignores its BitcoinTalk vommunity -- a community gathered right here, in this very thread.

Your explanation is reasonable, but you can't know for sure what's in their mind and they don't seem too interested about security. For example, staking can be done only with unencrypted wallets. PoW works with encrypted wallets though, but PoW revenues are just 10%. Why is PoS possible only with unencrypted wallets? To be able to lose your funds more easy?
