sm01@stt008:~$ dpkg --get-selections "*" > mylist.txt
sm01@stt008:~$ dpkg --get-selections > mylist2.txt
sm01@stt008:~$ diff mylist.txt mylist2.txt
< popularity-contest				purge

man dpkg:

--get-selections [package-name-pattern...]
Get  list  of  package  selections, and write it to stdout. Without a
pattern, packages marked with state purge will not be shown.

So, in b) as you did not provide a pattern (*) you don't get the "purged"
