I think his point was that they were not gaining as much in straights with open DRS as others, so they are not losing that much/at all with the new DRS rules.
though if they'll introduce 2 DRS zones every race, those will most probably be in straights where they were hitting the limiter... then I think we will see a new setup philosophy from them.
Red Bull are losing with the new DRS fules, because the places they were gaining were not the straights, but certain corners where they alone could open the DRS. That is the advantage they will be losing, gearing and top speed is another issue entirely.
I think that Red Bull will be forced to change their approach if they can no longer be reasonably sure of pole, and might therefore expect to have to do some overtaking. They will have to use higher gearing, as they did in Abu Dhabi for Vettel, and maybe remove a little downforce. That revised car was still pretty quick, but they are obviously quite certain that they get an advantage in race pace from the lower gearing, otherwise they wouldn't persist with it.
Some people will say "OK, but Vettel has proved he can overtake, so where's the problem?" The problem is that a low-geared car really struggles to overtake other cars which have similar pace and are on similar tyres, because it can't fully utilise the DRS That is the situation Vettel will most often be in if he can't put it on pole. Being able to overtake slower cars, or cars which are on much older or harder tyres, is not going to be relevant most of the time.
