I myself was surprised to see this arrangement when I looked at it yesterday.
Now, potentially the resistors might be used to discharge the interwinding capacitance, I am not sure why, but suppose this is an especially capacitive xfmr that gets charged to some voltage that can give you a little tickle, someone complained and they decided to discharge it.
The caps.....this might be a way to do the line RF filtering without exposing caps to the MAINs directly, so to avoid the danger of breakdown and completing the circuit between MAINs and GND.
Just a shot in the dark.
