What causes an engine to seize?
Taking the term most literally, an engine seize is when some portion of the engine has lost lubrication and the moving parts have started to abrade each other , either from friction, heat or mechanical failure (example: broken piston ring) to the point that the engine stops turning. An engine can seize due to simple mechanical failure, but generally that's referred to in a different way (throwing a rod, broken crankshaft) and in my experience 90% of the time loss of lubrication is involved in the failure along with everything else.
Why does the piston weld itself to the cylinder walls?
From there it's a race to see which part fails first: because the piston is where the fuel is being ignited, it will generally heat much more quickly, expand in the cylinder and start rubbing on the cylinder walls. This friction will quickly make things worse. In the majority of cases, the sides of the piston will weld themselves to the piston walls, stopping the piston (seizing it) in place and stopping the engine.

Can you disconnect the DME and crank all you want?
You could disconnect the DME and crank all you want without the fear of actually starting. Could also disconnect the wire to the coils or to the injectors.

As for turning the engine with a wrench, you need not remove it to do that. IIRC a 22mm socket fits the crank without removing a thing.
