It doesn't have to be. If in your current shell you have set PATH, but haven't exported it, then the command 'clang' would look in the PATH you have set, but 'strace clang' would look for strace in the PATH you have set, but strace wouldn't inherit that PATH, so it would fall back to the system default.
