Table 3-2 Note 3 includes up to 700uS of system delay, so even if the responder starts sending within the 2.0mS allowed by Table 3-4, it may not reach the controller until 2.7mS, which allows for a 3rd response.

In addition, inline devices can drop up to 7 bytes from the discovery response, so the minimum Discovery Response length at the controller is (17*44uS)=748uS. This allows a 4th response. It's VERY unlikely to happen, but possible.
