Therefore the effect of a load resistor on the L1 winding will also be reflected into the L2 winding.

That's what I think. But the voltage I'm seeing across L2 when it's open it's much bigger than the one across L1 even with the burden.  I'm sure they are both identical, i.e., same turn ratio. I will upload some graphs.
