Inconsistency between the sarif file and information from vscode codeql panel

I'm running a query. The vscode codeql addon gives the following analysis result.


From the image, i suppose there should be 8 paths in total. However, when i look at the sarif file, it only present four. What about the other four? The first and second thread flows belong to the upper one, third and forth belong to the lower one.

```json
...
"codeFlows" : [
{
"first thread flow" : [{}]
},
{
"second thread flow" : [{}]
},
{
"third thread flow" : [{}]
},
{
"forth thread flow" : [{}]
},
],
...
```
