According to ref guide for V$ARCHIVE_DEST_STATUS

APPLIED_SEQ# ...
Identifies the log sequence number of the most recent applied redo log received at the destination

So why do I get more than one row like the following

SQL> select applied_seq#, applied_thread#
2 from gv$archive_dest_status
3 where applied_thread# > 0;

APPLIED_SEQ# APPLIED_THREAD#
------------ ---------------
6625 1
6620 1

SQL>

From the ref guide I would expect to get *the most recent*
