Detailed Description

The checker looks for constructors that can act as copy or move constructors through their forwarding reference parameters.

If a non const lvalue reference is passed to the constructor, the forwarding reference parameter can be a perfect match while the const reference parameter of the copy constructor can't. The forwarding reference constructor will be called, which can lead to confusion. For detailed description of this problem see: Scott Meyers, Effective Modern C++ Design, item 26.
