No. The question is, which AudioBuffer(s) are associated with which
AudioBufferSourceNodes?

I think you need to say something like "An AudioBufferSourceNode N is
associated with an AudioBuffer B if N.start() has been called and N.buffer
was B when start() was called." (I.e., only the value of N.buffer at the
moment start() is called matters.)

Thanks,
