Is there any reason why Oracle does full table scans for online rebuilds and not for offline.

Online rebuilds don't use existing index for creating new. They do full table scan on the table.
However, in both cases, old index segment is kept until new one is ready to use and switch to it is done. Also the journal IOTs used for online rebuilds are stored in the target tablespace, so if you've got lots of transaction
on while you are rebuilding the index onl ine, you need additional space in target tablespace.
