Must have missed your earlier comment. Have you tried doing so recently? Assuming the failed drive in the video was just under a year old as he mentions when it was posted to YT? That makes the drive about four years old today. You don't think storage technology can change in that time?
Just did it with basically the same drive. 320 GB samsung 3.5" drive. Sure there were errors reading some of the files, but it was able to recover all of the lady's photos, which was the most important thing.
When it maps out bad sectors on the fly, it rights it into a table. This is not the firmware, but rather a small flash drive, if you will.
When it maps it out, it creates a re-direct to the original index. If you swap the boards, that re-direct is gone, so that file will effectively be gone or corrupted. Furthermore, the re-directs that are present on the donor board are still there and those re-directs can also create corrupted files by inserting a block that is out of place. Typically this is less than 3% of the drive as a whole and if the customer only has 1/2 the drive space used, then the chances of a corrupted file are cut down significantly to less than 1%
Now, with hybrid drives this gets thrown out the window. Essentially a hybrid drive is two drives made to look like one. Lose the electronics and the drive is scrap metal.
