Bonding and grounding are the same - if the thing you are bonding to is at ground already.
A good example of this is TVs which these days tend to be "floating earth", TV are mostly plastic now so the risk of shock is much less, plus the voltages in Leeds are way below the 25kV+ on the old CRTs. So there is no longer an earth wire in the mains flex. The TV has no idea what voltage "ground" is but it still works because the potential difference between live and neutral is still the same. It can mean that on a cheap set the aerial wire (for example) is at a different potential from ground, so be careful....
