In this case their use of the incorrectly-described A/B was probably exclusively to handle the (not extremely rare) instances of rackmount server power supply failures, to give each 1U or 2U size machine, or rack of blades, two live power supplies with live power feeds. Nothing more complicated than that.
And then inevitably the customer will load the rack with dual supply gear to the point that each feed is pulling over 50% of the breaker rating.
When one of the feeds eventually does have an issue, they'll immediately pop the breaker on the other one.
