1. 7.3 includes/admin.inc \views_ui_pre_render_flatten_data()

Flattens the structure of an element containing the #flatten property.

If a form element has #flatten = TRUE, then all of it's children get moved to the same level as the element itself. So $form['to_be_flattened'][$key] becomes $form[$key], and $form['to_be_flattened'] gets unset.
