I was a little disappointed to see that NEC 358.24 only says that bends "be made so that the tubing is not damaged." I suppose, though, that the further specification that the radius "shall not be less..." could apply to finding a violation to the sort of free-hand bending as is shown in this photo.
Why spend $8 for a bender, when you can tweak the pipe between studs, bricks, or a handy bumper? :-(
I suspect that one of the bends made is too small in radius to comply with code...and the EMT almost certainly has a "flat spot-" even if this guy stopped just short of a kink.
With workmanship like this, no one should be surprised to see that the EMT is completely unsupported, or to find #12 wires serving a 30 amp water heater (yes, he did that also.) And, of course, no ground wire- even though there is flex used.
