Multiple proxies with single logic contract

[brian-man]

What's the recommended pattern for deploying multiple proxies that use the same logic contract?

We're currently using the pattern:

// Migration M
const MyLogicContract = artifacts.require("MyLogicContract");
const firstProxy = await deployProxy(MyLogicContract, [], { deployer });

// Migration N
const MyLogicContract = artifacts.require("MyLogicContract");
const secondProxy = await deployProxy(MyLogicContract, [], { deployer });

After the second migration, build/contracts/MyLogicContract.json has the secondProxy address and the firstProxy address is not present anywhere that I can find.

The documentation on OpenZeppelin describes the behavior and indicates reuse is a first-class usage pattern, yet doesn't seem to reconcile the former (A) with the latter (B):
https://docs.openzeppelin.com/upgrades-plugins/1.x/api-truffle-upgrades#deploy-proxy
(A)

During a migration, the proxy address will be stored in the implementation contract’s artifact

(B)

If you call deployProxy several times for the same implementation contract

Thanks.
