AFAIK, Asterisk does not support simultaneous registration from more
than one device on the same extension.
That is why you are seeing this behavior. As soon as B tries to
register, the registration of A is 'overwritten'.
If you need this behavior, you might want to try and look into a
different UA Registrar like OpenSIPS, which supports this.
