It's for organizations that have different standards.
For example, the DoD has a pretty strict standard w.r.t. erasing traditional magnetic hard drives, even though `dd of=/dev/zero` should be good enough. Attacks at that point are theoretical, but they want defenses against theoretical attacks.
For one, the green button may not be fast enough. There are many ways flash cells can be killed en masse. Individually rewriting each cell would take much longer. Someone can then pull the plug and stop the entire process.

Why do I need the red button if the green button erases data sufficiently?
The red button is impressive but whats the benefit of trashing the SSD? Or does the green button not erase data with 100% reliability?

The red button works in a few seconds. The green one might take a few minutes.
