This not only allows for more efficient multitasking, but uses less power compared to initializing everything from scratch.
When you use RAM optimizing apps that arbitrarily force close apps, the OS will just re-initialize those apps again to refill the RAM. There's no way to prevent this, so those optimization apps and OS will just spend all day fighting each other, wasting battery re-loading apps only to be closed again.
That being said, I think Samsung has been going down Huawei's path in terms of more aggressive RAM management at the firmware level, hasn't it? The main problem this causes is that apps are more likely to be killed in the background, which can be a pain if you have an app in the background that you want to continue working (like a music or podcast app, for example).
