When Picard, Crusher, Worf and Captain Nu'Daq beam down together, both Dr. Crusher and Captain Nu'Daq materialize with their right leg slightly elevated and ahead of themselves in a step-like position due to the uneven topography of the beam-down site. The transporter pad they beamed down from is a flat surface. There would be no reason to keep one foot elevated.
When the Enterprise is supposed to be at warp, we can see on the viewscreen on the Bridge that it clearly isn't.
