Here's one possible explanation: the CSMA backoff changed between T1 and T2.
In T1, the CSMA backoff wasn't very fair, allowing one transmitter to
possibly hog the channel. The CSMA congestion and initial backoffs were
flipped in T2, making the initial backoff longer and the congestion backoff
I think he is talking about a shorter range and not lower
throughput. He says whenever he sends a broadcast packet, fewer nodes
receive that broadcast pkt in T2 than in T1.

Yes... though the scenario is reversed.
When all nodes are sending broadcasts, and one basestation is receiving,
that base station is receiving packets from *less number of nodes*.

About the scenario: If a packet is received by many nodes, a node will
have received packets from many nodes.
