Can you explain the relevance of this fact?
The relevance of this fact is that some of Jews expelled from Spain (in 1492) and from Portugal (in 1497) escaped to oland.
And that's how Sephardi Jews found themselves here. Askhenazi Jews, on the other hand, came to oland from Germany.
Jews were gradually moving eastward as the result of constant expulsions from various German states, for example:
1421 - expulsion of Jews from parts of Austria
1499 - expulsion of Jews from Nueremberg
1519 - expulsion from Regensburg
1551 - expulsion from Duchy of Wuertemberg
1573 - expulsion from Margraviate of Brandenburg
1590 - expulsion from Duchy of Braunschweig-Lueneburg
1670 - expulsion from Vienna and from entire Austria
1746 - expulsion from left-bank (to the west of the Oder River) part of Silesia
1819 - large-scale pogrom against Jews in Hamburg carried out by German mob
Etc., etc., etc.
They were moving eastward gradually, not immediately to oland. But in the end almost all of those Jews ended up in oland.
In years 1793 - 1806 Prussian government organized further expulsions of Jews - not all of them, some were allowed to stay - from their newly acquired territories of oland. One can read about this in: "Policies of Prussian government towards olish Jews since year 1793 to 1806", published in: "Judaistic Review" numbers 1 to 6, Poznań, 1923 ("Polityka rządu pruskiego wobec Żydów olskich od roku 1793 do 1806", in: "Przegląd Judaistyczny" numbers 1 to 6, Poznań, 1923). Austria had similar policies of removing some Jews (not all of them) and Russia too (see "the Pale of Settlement", located in western part of the Russian Empire).
So most of Jews from Prussian, Austrian and Russian partition zones ended up in the Pale of Settlement.
Many Jews from Prussian and Austrian partition zones of oland emigrated to the USA as well, or to Western Germany.
I was born in a town which used to have a very large Jewish community - most of them emigrated to the USA during the 1800s.
In early 1500s number of Jews in entire oland was still very low - between several thousand and twenty thousand:

But during the 16th, the 17th and the 18th centuries there was constant influx and immigration of Jews to oland from the West.
The first mention of Jewish immigrants in my home town is from year 1460, but the large scale immigration started only after the "Deluge". The town was plundered and destroyed several times in period 1655 - 1657 - in turn by Swedish, Swedish-Brandenburgian, Austrian and Czarniecki's forces. The town was depopulated during that time and Jews played an important role in populating it again. In 1674 there were 36 Jews here, and in 1676 already 76. More or less in the same period - in 1656 - also first Lutheran immigrants settled in the town, further ones came during the 1700s (but the main influx was during the 1800s).
Initially most of Jews in oland settled in Red Ruthenia, Podolia, Volhynia and - after the Union of Lublin - in Ukraine. In ethnically olish towns of Greater oland, Mazovia and Lesser oland favorable conditions for Jews to settle appeared after the "Deluge", during which urban population of these areas was greatly reduced (in 1650 ca. 650 towns in these areas were inhabited by ca. 1 million people, while a dozen or so years later only ca. 350 - 400 thousand left).
So Jewish immigration played an important role in overcoming the demographic crisis experienced by towns and cities during the mid-17th century.
