Because then you can reliably check `bufferedAmount` to avoid calling `send` when the buffered amount is above some threshold. It guarantees that `bufferedAmount` is always greater than or equal to the actual buffered amount.

For example:

```
while (haveDataToSend()) {
  if (dc.bufferedAmount > bufferFullThreshold) {
    // bufferedamountlow event will cause us to resume sending.
    break;
  } else {
    dc.send(getChunkToSend());
  }
}
```
