Aave DeFi on-chain voting process

I understand the scheme of on-chain voting correctly:

1. A proposal is made with the code (which will be integrated into various smart contracts) in the section https://github.com/aave/aip
2. When the code is approved, the on-chain voting procedure begins, which takes place exclusively on the AAVE internal website https://app.aave.com/governance/. Here, all transactions are sent to the on-chain network and therefore gas is charged for each vote. Correctly?
3. After the completion of the voting, the "freeze" period begins, when automatic execution still does not occur.
4. After the end of the freezing period, the offer is considered accepted and the proposed piece of code is automatically integrated into the smart contract.

Did I understand the point correctly?
