Why does bathtub drain leaking occur when tub fills much water?

I have a new bathtub installed. After I filled the tub lots of water and then drained it. I saw the drain leaking occurs under the tub. However, if the tub is filled less water, it does not have drain leaking. Is it because the much water the bathtub holds, the more water pressure the drain has? Can anyone explain it?
