DROP INDEX and CREATE INDEX on non empty tables both recreate the table and the data to reflect the new indexing structure. The new structure should be reflected in the DDL script, otherwise if a SHUTDOWN IMMEDIATE occures, the following will happen:
If the table is cached, the index roots will be different from what is specified in SET INDEX ROOTS.
If the table is memory, the old index will be used until the script reaches drop index etc. and data is recreated again. The fix avoids scripting the row insert and delete ops. Constraints that need removing are removed outside this (fredt@users)
