From Wikipedia: List of French expressions in English
beau geste
lit. "beautiful gesture", a gracious gesture, noble in form but often futile or meaningless in substance. This French expression has been pressing at the door of standard English with only partial success, since the appearance of P.C. Wren's Beau Geste (1924), the first of his Foreign Legion novels.[5]

Still not sure this helps explain it.

Can’t figure out how doing something which is noble in form but often futile or meaningless in substance can be elevated to an art. Or why it would be.

But most of all — have no idea what it means in this context.
