Incomplete Recovery After Drop Tablespace.

Question

Hi...some technical help required.
I was trying a hands-on for incomplete recovery. That is drop a tablespace and then retrieve back until 1 second before drop statement.
The Steps were like this...
1) Shutdown Immediate;
2) Copy all *.ctl, *.dbf, logfiles into a different folder <nis_back>
3) Startup;
4) Enter 3-4 Records and Commit. Table is in <USER> Tablespace.
5) 3 times "alter system switch logfile;"
5) drop tablespace users;
6) shutdown;
7) Check the Alter Log and find the time when tablespace dropped.
Suppose time when dropped is -> 21-Aug 10:30:45 AM. (HH:MM:SS)
7) copy back only *.dbf, *.ctl files from backup folder <nis_back>
8) startup mount;
9) alter database recover automatic until time '2002-08-21:10:30:40';
10) <<Statement Process>> Message Comes.
11) alter database open resetlogs;
When I open the table into which I inserted records just before dropping the tablespace I dont see the records (Inseretd in Step - 4) but the tablespace is back.
Now My Concern -> Why did the 3-4 record which I inserted in step 4 did not get restored from the archieve log ?
Hope to hear from you all soon.
Thanks in advance.
