Hi Marty,
The XYZ Wing basic premise is that at least one of r5c78 or r8c8 must be 5, otherwise the pivot cell r5c8 would be empty. By transporting the 5 in r8c8 to r5c7, it means that one of r5c78 must be 5 (that's the whole point of the transport - reduce the number of 5's that must be True). So any 5 that can be seen by both r5c78 must be False, including the 5 in r5c5.
BTW XYZ Wings don't seem to be easily explainable in terms of Eureka notation, so I didn't bother trying.
