Why do higher mpg numbers mean lower L/100km?

They measure the same thing in opposite directions. MPG is distance per fuel (higher = more efficient), while liters per 100 km is fuel per distance (lower = more efficient). They are inverses: 235.215 ÷ mpg gives L/100km in US units. Also note US and imperial gallons differ — 1 imp gal = 1.201 US gal — so UK mpg figures are about 20% higher for the same real consumption.
