You have exactly the right interpretation here. Interpolation was only intended as a way to get going quickly and easily with lots of addresses. And it has another use: Some non-OSM data sources use a format where a "street" has attributes giving the house number range on the left and right side. This can be reasonable easily be transformed into the addr:interpolation format for importing that data into OSM. It is here like with everything in OSM: There is a trend towards more detail. If you have more detailed information, great. If not, it is better than nothing.
