5Gbps PoE+ Injector question

So I purchased a 1Gbps PoE+ injector and was testing it using my PC that has a 5-speed NIC (10G/5G/2.5G/1G/100Mbps). I noticed the link speed is showing 5Gbps when using the injector as a bridge between two PCs with 10Gbps NICs. Basically I am ignoring the PoE function and just using the data in/out ports to connect two PCs.

My question is how come the link speed is showing 5Gbps, and I'm also curious to hear any theories on why the manufacturer used more expensive hardware components but only marketed it as 1Gbps.
