No, it's just how the diff get generated with the context :). 

The only material changes of this patch for this patch file are the ones that you see with ++ (for line additions) or +- (for line deletions). In this case, what you see is actually that ```<kiji-schema.version>1.1.1-SNAPSHOT</kiji-schema.version>``` is replaced by ```<kiji-schema.version>1.1.0-opower-1-profiling</kiji-schema.version>``` along with the (unchanged) context surrounding it. I know it's confusing but that's the fun or reviewing patches to patch files.
