When set to "Off" the file numbering will be reset to 0001 when a new
folder is created, the card is formatted, or if you put a new
(fresh/different) card into the camera. A new folder will be created if
the current folder contains 999 shots.

You can't change horses in midstream without some consequences.
If you had turned the sequence option to "On" and then formatted the
card in your camera you should have a single folder and you should have
a numbering sequence running from DSC_0001 to DSC_9999.
Changing the option without formatting the card is going to result in a
new folder being generated.

Renumbering and moving files back onto the card is not a good idea.
Set the option to "On" the numbering sequence will run from from
DSC_0001 to DSC_9999 before the camera creates a new folder and
restarts the sequence. That will happen regardless of any further card
formatting, using a different card (reformatted or not) or a new card.
Note: using a different card which has been used, but not formatted
after filling a card, will continue the numbering sequence where you
left off on the prior card, provided your folder numbering is the same
on both cards.
Formatting the card is not the same as resetting the numbering
sequence. If the numbering sequence option is set to "On" and you
"Format" the card, the numbering will remain intact from the last shot
taken.
If you "Reset", a new folder "101" will be created and the numbering
will restart at 0001. this is useful if you want to retain a numbered
sequence for a particular event.

The shots taken before you have developed a consistent numbering system
for yourself will just have to be renamed and/or numbered on your
computer independent of any subsequent shots you take.
Personally, I have the numbering sequence option in my D300S set to
"On". Once I have backed up the contents of a (full or partially full)
card to my computer and my redundant backup system, I "format" the card
in the camera. The numbering sequence continues from the last shot.
