As you state (emphasis mine):
the reasoning against these smaller acts of loyalty to the "state" or ruler, such as the Nazi salute
Jehovah's Witnesses are only loyal to Gods Kingdom, as Jesus said himself (John 18:36):
My Kingdom is no part of this world. If my Kingdom were part of this world, my attendants would have fought that I should not be handed over to the Jews. But as it is, my Kingdom is not from this source.
Jehovah's Witnesses do not take part in this world's politics and they don't 'take their sides' in conflicts. They don't declare their loyalty to any other government then Gods Kingdom, no matter how small.
Jehovah's Witnesses have "deep respect" (1 Peter 3:14) for the government and their officials, and they listen to them as long as they don't ask us to disobey Gods laws.

The phrase "Heil Hitler" roughly means salvation belongs to Hitler. Ascribing salvation or allegiance to Hitler would be a form of idolatry.
The Bible states in ps 3:8 Salvation belongs to Jehovah
Salvation is not to be ascribed to human institutions or their symbols (Exodus 20:4,5) (1 Cor 10:14)
