What’s good for the goose is good for the gander -or not? :)

Hi

What is sauce for the goose is sauce for the gander
or the version from the thread name is a 'standard' idiom.

But I've also met
What’s good for the goose is not good for the gander.
- which is the truth, as well

(In Russian there are some idioms that play this thing. Two opposite meanings, both self-valued )

Can I consider them both as separate idioms?

Hi Tamara
I know the equivalent of this proverb in Russian, either
I don't think they are of the same meaning because in the second its meaning is contradicted to the first one, as you mentioned. I think the second proverb corresponds to

What's good for one is bad for another
