What you observe is what will happen if you delete records using
DELETE statements that have a WHERE clause.

If you empty the entire table at once like this:

DELETE FROM tbl_name

then the AUTO_INCREMENT value will reset to 1.

This is true for MyISAM tables, not necessarily for other table types.
