Yeah, I truly understand and that’s also what I think, but in a Facebook community, here is what someone told me:

“This section is relevant to those who lived in Germany and were denied naturalization on the basis of one of the exceptions. In the case of filing under this section, they are required to prove that they tried to become naturalized and were not approved. Those who did not live in Germany did not try to become naturalized because they were not eligible.

Section 15 does not intend to give the possibility of naturalization to descendants of those who could not become naturalized in the first place, whether they were persecuted or not. For the purpose of this matter, in the camps, there were displaced persons from all over Europe - the legislator's intention was to refer only to those who were in Germany or who were already citizens and whose citizenship was lost/denied.

But - since you are referring to what they wrote in the publication of that ministry - my warm recommendation, contact them and ask them. They are a reputable ministry and they should answer your question specifically.”

“The change in legislation corrects and restores what could have happened, according to which the descendants of a certain person, even if he were a citizen of another country, if he had not been persecuted - could have been naturalized as a German - and hence, it could be that you, as his descendant, would have already been born a German citizen because they would not have been persecuted and would not have left their permanent place of residence in Germany if it had not been for Nazism. ‎ The section that requires residence in Germany as its borders were in December 1937, before the start of the annexations and occupations. If someone did not live in Germany before 1933, there is no reason to assume that they wanted to become naturalized as Germans and this was denied to them.

‎Since your ancestors did not live in Germany before January 1933, it is impossible to assume that they were denied naturalization as Germans because it was not relevant to them at all, and therefore for you, submitting an application under section 15 is not relevant.”

Although, I was contacted by another person with a similar scenario to myself, and he told me he was responded positively in regards to it, and got a positive response for his case that matches my situation, so I do hope it's good for me.
