Have a read of the original article. It questions that whole premise that losing salts is a problem. IMHO, the evidence in that area is limited and often contradictory.
The evidence in this whole field is pretty scant really. For example, most people think electrolytes help with exercise induced cramps, and yet the only thing with any evidence to support its use is actually pickle juice (!)[1][2]. There is very little evidence to show electrolytes help with cramping in trained athletes.
