you'll only be able to run 2 corridor of landing and 2 corridor for lift-off at all time
2 not 4. You both take off and land into the wind. So you'd only have 2 "runways" at any given time, one on either side of the circle. Say the wind was blowing perfectly north to south you'd have 2 "runways" facing due north. Once you start deviating from this you are creating crosswind landings which is against the core design principle.
The quoted number of 3 simultaneous operations only exist in a zero wind situation. If there's any wind one will be fine. At least two will have cross winds. The only way to avoid the third "runway" having a tailwind would be to have all three with a crosswind. Which as mentioned is against the core design principle.
The designer clearly has no aviation experience.
