The phasor has nothing to do with spatial direction of the field vector.

Sorry, but The IEEE Dictionary disagrees with you.
In the description of the Poynting vector, it says:
"E and H are the electric and magnetic field vectors
in phasor notation ..."

I have prepared a graph of a snapshot in time of
a forward wave and reflected wave of equal magnitudes.
When the waves are superposed at the reference plane,
the total E-field and total H-field are 180 degrees
out of phase. The graph is at:
