Although the SEQUENCE parameter does not require that THREAD be specified, a given log sequence always implies a thread

Does this mean that the log sequence is unique for all threads ? If not what does this sentence mean ?
Note that in my 10.2.0.1 RAC database log sequence is unique only for a given thread:
  1  select thread#, sequence#, name, status
  2  from v$archived_log
  3  where sequence# between 34 and 35
  4* order by sequence#
SQL> /
   THREAD#  SEQUENCE# NAME                                                         S
         1         34                                                              D
         2         34 /u02/fra/RAC/archivelog/2010_08_20/o1_mf_2_34_66xb2ttb_.arc  A
         1         34 /u02/fra/RAC/archivelog/2010_08_20/o1_mf_1_34_66xcgmbn_.arc  A
         2         35 /u02/fra/RAC/archivelog/2010_08_20/o1_mf_2_35_66xb48b8_.arc  A
         1         35 /u02/fra/RAC/archivelog/2010_08_20/o1_mf_1_35_66xcgkk0_.arc  A
         1         35                                                              D
6 rows selected.

Answer 1

I sent mail to the writer and got this in reply:
The sentence will be rewritten to state that: "When you do not explicitly specify a thread number with the sequence number in the command, thread number 1 is used."
