I disagree. Warehouses like this actually do the opposite as what you are stating. The lack of interior bearing walls, methods of roofing attachment, and methods of exterior wall attachment of warehouse buildings means that a violent tornado is likely to remove the building skin and roof within second. It would be akin to peeling off a sheet of paper, leaving the structural frame completely exposed. Once the structural system is completely exposed, there is no "wind catching" whatsoever. The deformation you are seeing is the winds deforming the structural system with whatever PSF is required to deform the steel. In general this is 35,000 PSI of force, which is produced by 306 MPH winds.
Lets clarify removal of anchor plates as well. Anchor plates are the means by which steel columns transfer load to the foundation structure. Steel beams are connected to said columns using moment connections or fixed bolted connections. In this case because seismic is not a concern, fixed bolted connections are likely being used. If a steel frame, which acts as one rigid body, is being deformed to the point of collapse.....you can bet an EF-5 is the culprit. Winds below 200 mph are simply not enough to mangle a low-story, wide base steel structure that has beams up to 2'-0" deep. Focus on the structural system, not the overall building damage.
Wind catching is more of what you are seeing here: Where a structure is so tall that the wind exerts large amount of force on the upper half of a structure that the mid point deforms. In this case, it absolutely does NOT take 35,000 PSI to deform the steel because there is additional force being generated by the top heavy structure moving laterally.

EDIT:
Here is a great video that illustrates how insane it is that a steel structure can be deformed to the point of collapse by winds. This is our famous gas station video of hurricane charley. it is widely assumed that winds in this video reached somewhere between 140 - 150 mph sustained. That is well below the EF-5 threshold obviously, and notice what happens to the steel frame: Nothing. The same kind of process happens when a tornado hits a warehouse building. The skin is shredded leaving the structure exposed. Whether that structure gets deformed further depends on the wind / PSF generated. Here it was below the threshold to bend steel. In Mayfield it clearly was not.
