what would the purpose be to go try line 1...

If somebody jumped in the middle of the hunt group. Say they called line 2 or line 3, they were busy but line 1 was idle. That's not something that will happen here but does with regular numbers and CID that reflects them. Somebody hits redial and the call comes in on line 3 because they were called from line 3.

If you only have three lines someone redialing line 3 makes you effectively have only one line unless there is circular hunting.
