Layer4 takes VCC as reference plane, atlast signal returns to respective
ground through decoupling capacitor
Layer6 takes nearest plane(depends on stackup) as reference, if it takes VCC
as reference then the signal returns to ground through decoupling
capacitors
Hope this helps

Hi
I have a question.If we have stacking sequence given below.Return path can
be VCC plane (provided it's not broken) or Gnd plane.
TOP
GND1
LAYER3
LAYER4
VCC
LAYER6
GND2
BOT
If Layer 3 takes GND1 as return path, What will be return path for Layer 4 &
Layer 6. Why?
Can anyone explain the theory / mechanism.
Thanks
