The "window" angle is when the entry angle at the boundary is the same as the exit angle on the otherside of the boundary. This angle is a combination of the critical reflection coefficients angle of each of the two sufaces.
This applies to any two different mediums for example "water and air".
If the top of the plug is on the boundary of air and water then snells window does not apply because the light rays will bounce into the air and not the water. However, if submerged well that may be when color gets reflected into the water and snells window will apply
