Nope, neither.  When the engine "seizes", overheated metals have
bonded to each other.  If it were simply a matter of "metal
expansion", the engine would free up once it had cooled down and
contracted.  Lack of oil or lack of coolant can both contribute to
said overheating.

You are clearly living in a theoretical fantasy world. An engine that seizes
up due to overheating will normally lose power and stall a hell of a long
time before the metal fuses together LOL. I've had engines seize on me at
over 70mph due to overheating which caused no noticable permanent damage.
