It was a historical reference using the terminology that was in current

There are many variations of the technique, but the idea of directing
the heat at the board is to minimize the heating effect on the
components. The most appropriate method depends upon whether it is
primarily the component or the board that is to be salvaged.

Yes, some mechanical assistance is usually necessary - molten solder
has considerable surface tension. If the component is a suitable shape
and size, I generally grip it with something and apply a gentle pulling
force at the same time as the heat.

That's a given with any such drastic measure :) I have used it
successfully quite a lot though. The usual disclaimers apply, obviously
- don't apply heat or flames to electronic components or apparatus
unless you are aware of all the potential hazards, including but not
limited to explosion, release of toxic fumes, burns, damage to
surrounding buildings and domestic harmony (especially when using the
toaster oven without the consent of it's primary user)
