I had thought the same thing.

However, last night, I tried something else which someone had suggested 
here: I moved, slightly, the position of the last bearing we took about 8 feet 
further to the west. Doing so made this "odd" bearing swing around to in line 
with the 4 "good" bearings.

Obviously, something nearby was causing the ambiguity and by moving, 
even slightly, the position where I took the bearing resolved the "oddness".

I was surprised, but pleased.

I think the reason may have been the overhead wires from the pole to our 
home, which were only about 10 feet above the loop until I moved further 
towards the street.
