It takes a lot of people by surprise, but that's how it works. Groups behave the same way. Unlocked images revert to their native dimensions and groups revert to encompass their contents if they aren't locked. If locked, both retain their set sizes.
For images, it allows you to scale an image temporarily and not worry about setting it back to its normal size when you return to the card because that will happen automatically. Another common use for the behavior is to re-use an image object repeatedly to show different photos, for example. When you put a new photo into the image object, it automatically resizes to accomodate the entire image (which is a very easy way to find out an image's dimensions too.) For groups, moving or resizing any of the contents allows the group to adapt immediately to the size of its contents which may or may not be what you need. In either case, locking the image or the group prevents resizing.
There have been discussions about which way the default should be, but it's a toss-up. Different applications require different behaviors and it usually works out that about 50% of developers want it changed.
