His statement...He didn't say that.
Simply, one configuration has 44 gallons more fuel than the other.
And using a second tank increases drag by an unspecified amount.
OK - I get itAircraft that could carry two drop tanks had the wing tanks deleted, so they carried 237USG in the main and 170USG in each drop tank, total 577USG. A unknown portion of that extra 44USG would have been burnt overcoming the extra parasitic drag of the extra drop tank.
