The PS3 issue described in the video was more specific to it, but similar in it's nature.
TLDR from my very imperfect memory:
The whole board-solder-chip sandwich expands at different rates due to heat, so internal stress and cracks develop in solder joints, which makes them fail. Baking PCB in an oven does something like making the crack close a bit, so that the solder joint works again.
Problem is, neither the crack, nor the internal stress that has been built up is gone, so the solution actually doesn't last.
