because ui.panel is a dom element, and you are searching for "a" within
ui.panel. panel isn't a class name for a "ui" element, it's the node
reference.
If it were $("a, ui.panel") it would be what you described with the
comma. The quotes are around the selector, and the comma means a second
parameter.
