Probably some guy doing his church a "favor" by installing that mess, probably free labor on some Sunday afternoon and he wanted to get it done, go home, and have a drink. Really sad that anyone in the electrical trade would lack the professional pride to do a hack job like that.
looking at that picture again, that cable's in a perfect spot to get weed-whacked once that little garden patch gets overgrown mad

As a side note, shouldn't your faultsman have done a little more work to locate the fault that caused that phase to fail? If something caused a new feeder to a building like that to blow a fuse/breaker then there is obviously a problem somewhere...
