You can apply the same thing to people management. Who cares if you're a shit manager, if you've managed 100 people that's still going to be looked upon more favourably than someone who's managed 20 people really well for a 100 person management position.
Applying it to execs is probably a simpler comparison. Shit exec means you were still an exec, so you can probably get hired somewhere else as an exec.
