SPAN ports IP addressing

Just wondering if a SPAN destination port needs to be on the same subnet at the devices on the source SPAN port?

For example, if I had computers with IP of 192.168.1.1 and 192.168.1.2 on the Source ports mirroring into a Destination port with a computer of 192.168.2.1 running Wireshark, will Wireshark still be able to pick up traffic?

TIA.
