It's only to prevent arcing on the battery terminals, which is a precaution against igniting any hydrogen gas at the vicinity of the battery caps and/or vents.
Most smart chargers are "OFF" by default and will only turn on manually via a switch/button or via logic after it has detected a battery present. This prevents arcing and so, clamping directly on the battery terminal posts is acceptable.
If you're using dumb chargers, connect the battery clamps first before turning on the charger. When finished, turn off the charger first before removing the battery clamps. To forego that sequence, mount the negative clamp on the chassis or engine so any arcing won't be near a hydrogen gas source.

I don't quite agree with that.
There are inherent risks when charging FLA batteries that has a lot to do with hydrogen gasses and arcing, which I already covered a few posts back. But as far as other electrical/electronic devices, the order in which a device is connected and powered depends on the specific equipment.
As per your example, laptops can be powered up before (ie. on-battery) or after the AC power is applied... it won't matter.
