By default this property is true when the source Panes are already within the Infragistics.Windows.DockManager.DocumentContentHost. However once the pane is dragged into a floating position, it's PaneLocation would be Floating and it would be treated like other dockable panes so dragging back over the DocumentContentHost would display a single docking indicator where the center is used to add the pane to the active document's tab group and the outer parts of that docking indicator are used to dock to the inside edge of the Infragistics.Windows.DockManager.XamDockManager just outside the DocumentContentHost. When set to a true, a docking indicator will be set over each Infragistics.Windows.DockManager.TabGroupPane within the DocumentContentHost.
