Its a CYA for SUSE. Certain technologies aren't permitted to be shared outside of USA unless you go through the ETAR and assign if it commerically restricted/unrestricted, etc. If you are in USA you are bound by this anyway, even without a EULA.
They don't know what you may install or transfer, even though it is opensource and you could download in another country.
We get hung up with this at work. We may have a software issue and send to USA parent company for review, they then need to know if the data represents a certain class so they can direct where (country) the software review or fix can be sent for evaluation.
There are obious things like military, but then there are commercial, transit infrastructure, aero, etc.
But it can get stupid, like the parent company received a CAD file I sent in as a demomstration of a display bug. i made a cube 4x4x4. the agent wanted to know what ETAR class it was, I argued it isn't because it is a cube I made as demo only, they would not review till i choose a class from a long list. None applied. But I had to pick one for them to proceed. So somewhere some guy is doing data chain of custody on a cube. lol
In cases where it does fall into restricted commercial interest or other restrictions only a USA citizen can work on the data.
This agreement poses no restrictiona on you that aren't already present if you are in the USA. And you shouldn't need to worry, unless you actively are designing or stealing data to hand over to a USA "enemy" for purposes of espionage , war, weapons etc
