I think the upper and lower bounds were created from the input to the user interface or API. The upper bound would be the nominal value plus the uncertainty, and the lower bound would be the nominal value minus the uncertainty. According to the data model (https://www.mediawiki.org/wiki/Wikibase/DataModel#Quantities) the quantity is stored in the data base as three numbers, the amount, the upper bound, and the lower bound. In this simple-minded model, the upper and lower bounds would be exact, absolute limits. (But in real life most quantities with a well-studied uncertainty will be points on the normal distribution, often plus or minus two or three standard deviations.)
