they do mean the same: a primary is more important than a secondary which is more important than a tertiary. This is how they are defined. There are no global expectations for surface quality, road widths, junction construction or similar physical properties. Take a bakery: the tag is worldwide the same, but the kind of bread is different according to the local culture. Even natural features may differ a lot, e.g. natural=peak. It could be snow covered the whole year, have steep sides leading to it, or be a relatively warm place throughout the year, have flat sides etc. It does not mean we would have to use different tags for these. If the definitions have been drafted with the whole world in mind, reduced to the minimum needed to characterize the core of the meaning of the tag (and possibly refraining from "examples", which are only limiting the idea into a certain direction and context), we won’t need a new tag for every local occurrence of a thing. On the other hand, we should never "re-use" a tag that is used for something else (according to which property/ies the tag should describe), just because we do not have the thing that the tag originally describes, in our context (i.e. just because it is "free").
