Actually it doesn't work out that way. You're still heating the plug
body fast enough to avoid softening the cable inside.
What it does guarantee is a good solder joint to the plug body, down
through the full depth of each hole. Many so-called "soldered" PL259s
have a good joint to the braid, but only a cold joint to the body.
