Why does this help my Titan Memory?

The impressive thing is that it manages the cache so tightly.
It actually reclaims almost all the memory it used when I close programs. The only time I see unexplained lost memory (leak) is when I wake up in the morning. Before it seemed to leak all day long.
I only really need to use Oxios for the non-Titan programs like HTC Album.
