Here is a post from another thread that addresses this topic:
Two reasons
1) You may have noticed how submarines are shaped - not especially long, nor sleek. Not very hydrodynamic on the surface but highly so when submerged
2) The underwater dolphin works best at high cycle rates. Tall swimmers with longer body sections to articulate can find it more difficult to match the rates achieved by shorter swimmers - think Misty Hyman vs some of the willowy 6-footers you see so often at Nationals in the LA strokes.
I'll buy 2, but not 1 on this issue.
