never heard of it but the names used by manufacturers differ
from a google search i think it makes sense now
the wire is used inside the drum to stop the end of the heater from waggling. if this was not in place then as the machine bounced on spin the heater would move and could contact the drum
have attached a pic. this is what I believe to be the correct way up (could be wrong ) and the heater will go in the end from the arrow
