how can you be so certain? Unless one clicks on a "paying" link (on their own site), there's no way to know for sure.
[edit: Zygoot beat me there by a minute :)]
For such cases (two ads can be displayed, but only one paying ad available), I assume G displays a PSA as 2nd ad to keep the layout structure.
Just my $0.02
