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.
