cppcoreguidelines-rvalue-reference-param-not-moved false-positive for assignment operator?

[EugeneZelenko]

I may be wrong, but looks like cppcoreguidelines-rvalue-reference-param-not-moved produces false positive when assignment operator with rvalue is available (https://en.cppreference.com/w/cpp/string/basic_string/operator%3D):

#include <string>
#include <vector>

std::vector<std::string> tokens;

void function(std::string&& token)
{
    tokens.resize(tokens.size() + 1);
    tokens[tokens.size() - 1] = token;
}
