It seems the NAND boot runs well by luck.

The ROM will do the swapping when it reads the BBT table written by the 
kobs-ng (or something else?).

If the BBT table is small, not bigger then a page, the NAND boot may 
runs well when you disable the swapping;
But it the BBT table is bigger, the ROM will get a corrupted BBT table.
