Broadcast frames are sent to all devices in the same VLAN, not just a single uplink. When a switch receives a broadcast on one port, it floods that frame out all other ports that belong to the same VLAN (excluding the incoming port). That means every access port and the uplink port in that VLAN will receive the broadcast. So the statement that a switch sends broadcast packets to the uplink port only isn’t correct in standard operation. The only times broadcasts wouldn’t reach the uplink are when the uplink is in a different VLAN or when features like port isolation/private VLANs restrict flooding to some ports, but typical switching behavior is to flood to all ports in the VLAN.
