It should be appropriate to also mention that might only be true for the vehicle being discussed, if we take this guy's word for it. Honestly, there's not much meat to that claim yet.
Here's an interesting paper with a lot of info:
THE ROLE OF TYRE PRESSURE IN VEHICLE SAFETY, INJURY and ENVIRONMENT

Table 7. Effect of under-inflation on rollover threshold
This simplified analysis suggests that moderate to severe under-inflation has
negligible effect on rollover threshold. Even extreme under-inflation of 100kPa
only results in a 3% reduction in the rollover threshold.
Under the dynamic situation the effects of under-inflation on rollover
propensity are likely to be more pronounced. This is because manufacturers
go to a great deal of effect to tune the suspension characteristics to match the
recommended tyres at the recommended pressures. Quite subtle dynamic
effects from under-inflated tyres can be magnified by the complex dynamics of
vehicle motion. However, this review could not find any quantitative research
findings on these dynamic effects.
