It largely would depend on the specific mission it was asked to carry out.
Having multiple launch positions and a separate recovery runway roughly corresponds to ability: to launch large packages of aircraft for some coordinated set of missions in the same timeframe; and to perform continuous recovery as needed when returning package run low on fuel. There isn't really need to be such capability in carrier ops, for the most part except large offensive ops to targets that are generally far away and/or well guarded by defensive layers.
If you just want to do low intensity sea control, run cap, or do asw missions, generally you wouldn't need that. If you actually want to send packages of attack planes to penetrate AD of an opposiing CSG, then that would generally be required. But for a ship that send at most a couple dozen in a package, usually much less, it's kind of a suicide mission anyways, if not backed up by numerous other land based missiles and aircraft and subs.
Another way to look at it, if a flattop has a launch position outside the landing strip, that carrier is usually capable of performing the long range strike / offense role (CVA in old USN parlance). In that case, you are able to continuously do recovery op, and at the same time periodically launch other necessary sorties such as CAP, AWACs, ASW, etc. You certainly would not need that for the typical types of helo missions in amphibious assault or CIS (whose aircraft are generally designed for loiter anyways).
