In this case South's double shows a fair amount of points. I suppose advancer is allowed to pass to show indifference to the two options, but then overcaller has to bid. In this case overcaller can bid his 6-card suit.

In this case South's double showed rebiddable clubs. Clearly someone has to bid again.
