Marriage laws in 1953 in Poland - foreign WOMAN married a Polish MAN in HER country

I'm not sure if anyone can answer this question but here it is:

In 1953, if a foreign WOMAN married a Polish MAN in HER country, did she renounce Italian status and become Polish?
Or is she still her original nationality?

Thanks for any help or guidance!

As published in Ustawa from 8th January 1951 about Polish Citizenship, Article 10:
1. A foreigner may be granted Polish citizenship at his request.
2. Polish granting of citizenship may depend on submitting evidence of exemption from foreign nationality

But here is the phrase "may depend" - so it could mean that it wasn't always necessary?
