I find a couple of things troubling in that article. First, joints MUST fit perfectly for a good solder joint. If not, the solder will actually release gases at the joint. That's what causes pitting at the joints. 

Secondly, when solder is heated and flowed, some of the alloy is burnt off making that joint 'a little' harder when reheated for additional soldering. It is all about heat control. That's why some people can use the same grade of solder on multiple joints.
