Except that they didn’t go over the top and drop down to the other side without breaking a leg, which is arguably the most important part if you are going to claim you defeated a fence.
Twenty five years ago I was taught the average barbed -wire topped chainlink fence ten feet high would delay a team of three or more less than a minute,using only a blanket or tarp,maybe a poncho..Hardly a full solution.
Not to worry -- any well-equipped crossing party would be armed with ladders, ramps, or even a convenient crane -- all of which would be quicker and safer. And of course, explosives (readily available among the Mexican criminal element) would take care of the problem entirely.
