Is it OK to remove shared_ptr reference to itself

Is it safe to remove the only shared_ptr reference to itself inside a method? Something like the following. If two objects, one of class A and the other of class B, points to each other via their pB_ and pA_. Suppose pB_ is the only reference to the object of class B. Then I call A::method() on the object of class A. Will there be any problem?

#include <iostream>
using std::shared_ptr

class B;
class A {
 public:
  void method() {
    pB_->method();
  }
  shared_ptr<B> pB_;
};

class B {
 public:
  void method() {
    pA_->pB_.reset();
  }
  shared_ptr<A> pA_;
};
