To my understanding, the REFRESH statements "merely" update the version information stored in the related objects. They do not change anything else; and the REINDEX does not reference them in any way. I suppose the REINDEX goes first as it does the actual fixing of now-invalid objects by rebuilding them. After that one is back to a usable database state, even if left with pesky (albeit harmless) warnings on version mismatches -- which to get rid of one runs the REFRESH statements. Or so my understanding... Which is why my question still stands: does the above three-strikes operation safely take care of any collation issues that may currently exist in a database ?
