BGP route Path

I have below ADPVN with BGP Topology.

Spoke1 and spoke2 have 3 connection using different provider, two using internet connection and one using dedicated wan.

Since we use different wan connection on spoke1 and spoke2 there is no shortcut tunnel across spoke.

When both internet on spoke1 is down, i believe the traffic from spoke1 to spoke2 can use wan connection. Am i right?

But if i do show bgp routing details to spoke2 on spoke1 i can see valid route only via shortcut tunnel and no route to spoke2 via wan connection. Anyone know why?
