IST and VLAN assignment

in encor ocg,there is this topology https://ibb.co/44NGvXh,correct me if im wrong, why sw1 to sw2 links are access not trunking?!! why would you do that , access ports dont send BPDUs right?i dont understand why Gi1/0/2 is blocked is it normal STP forward blocking process negotiation , the book:

It appears as if traffic between PC-A and PC-B would flow across the Gi1/0/2 interface, as it is an access port assigned to VLAN 10

i gone through the [cisco 802.1s whitepaper](https://www.cisco.com/c/en/us/support/docs/lan-switching/spanning-tree-protocol/24248-147.html) and i encounters the same exact topology and explanation, can someone clear this to me thanks
