It's true.
The combustion process is not a result of heat like in a car engine. It is a result of a chemical reaction between the alcohol in the fuel, and the platinum in the glow plug's coil. Heat simply assists the reaction.
So while it is unlikely, it is DEFINATELY possible for a warm engine to start without a glow driver attached.
Sorry but I also replied to a thread a week ago about Pt in glow plug but did not hear back.

I doubt that Pt is used in glow plugs, can you guys give me a reference where it says Pt is used in the glow plug.
Pt active catalsyts are used in methanol oxidation but doubt that Pt is used in the glow plug and also doubt that even it is a catalytic reaction taking place with the glow plug.
