This makes no sense though? Given the Nyquist theorem, simply increasing sampling frequency past a certain step doesn't change the outcome.

Actually, it does. You can decimate the higher sample rate to increase dynamic range and S/N ratio.
Also, for direct down conversion, you can get better mirror frequency rejection by oversampling and filtering in software.
