Not entirely - when you are online but somewhere else, it will keep chunks loaded.
Since most people log off when they are at home, that means when you log in, you activate those chunks - and world anchor will keep them loaded if you leave the vicinity. This means machines in your home or base will still be functioning if you are elsewhere, and is especially good for certain setups like my IC machine. I have 160 chests feeding into an ender chest, and the world anchor means that those chests will feed while I am at the bank using an ender pouch because those chunks are loaded. This does not work well without the anchor, because those chunks unload when you depart, leaving the ender chest without a supply. That is my personal experience, anyway.
