TCL culling is part of the tcl engine and hence ignored if there's no TCL. But viewport transform (which is where the fbo inversion happens) is done later, hence TCL culling is not subject to that inversion. FWIW it would also be possible to simply disable TCL culling, setup culling is enough. The docs are actually saying it TCL culling is a performance optimization with questionable quality (as the coords aren't snapped to rasterizer subpixels). I guess it would also be possible to disable setup culling instead (of course only with tcl) but I'm not sure if that would make any performance compared to having enabled culling at both places.
