Move to SD size change...

When I move my downloaded apps to the SD, I see that the file size decreases dramatically. Is this normal? For example, when I moved angry bird to sd, the file size change from 21mb to less than 3mb.

The reason why is because the 18mb of the app is stored into the SD card/internal storage while the 3mb of the app stays on the phone (probably the main codes of the app).
