Her proper saddle height likely means that she can't reach the ground while seated on the saddle. This means that when she stops, she needs to both unclip and get out of the saddle. She might even need to lean the bike slightly so that she can straddle the top tube while standing on the ground - or while standing with one foot on the ground and the other foot clipped in.
