They are indeed the same clone, according to the USDA references below. I don't know why Fuggles grown in the former Yugoslavia are called Styrian Goldings. The USDA just calls them Styrian, without the Goldings part.
Goldings are a different variety, usually with that name prefaced by the name of the area of their growth, whether that be East Kent, West Kent, Yakima, or wherever.
The old saying is that beer is made, and wine is born. That's based on the effect of soil & climate on the grapes. There is some of this for hops, too. You'll probably get some "born in Cochrane" character in whatever hops you grow. However, variety still matters, and of course you have hops addition timing, malt choices, yeast choices, mashing temps, & plenty of variables to influence the beer you craft. It could be fun to try matching brews with the only difference being locally grown Fuggles versus Styrian. Gordon Strong might know the difference; I doubt I would.
Do they grow well there?
