modifyDataType does not auto reorg on DB2

In my case (DB2 9.7.0.2) liquibase runs successfully for the following changeset:

<modifyDataType tableName="ATABLE" columnName="ACOLUMN" newDataType="DECIMAL(23, 4)" />

Nevertheless, it doesn't add REORGs when running updateSQL. This changeSet should work without them on DB2 9.5, but will most likely fail on 9.7 (REORG has to be called every three alter statements).
