Why doesn’t Multiset allow to erase just one sample?

The reason lies in the official definition of the erase() method in std::multiset.

size_type erase (const value_type& val);

where val is the Value to be removed from the multiset. All elements with a value equivalent to this are removed from the container.

So if you use a value as a parameter in the erase() function in a multiset, then all elements having same value than this passed value will be erased.
