Solr score diff in doc list and Explain score

Question

I am getting a list of docs when hitting my solr query. Strange issue I am facing is that when I am trying to explain the score calculation for a document then the score is coming different in what is shown in the doc list.

Example: score for a doc in the

"docs": [{
    "id": "1DMOXQ3VN7FF",
    "score": 6.7063313
},
{
    "id": "6WNYN6NVVPDU",
    "score": 6.699659
}]

Now the score for the doc in id when I try to explain it

 "6WNYN6NVVPDU": {
                "match": true,
                "value": 10.562147,
                "description": <some score calc logic here> 
}

You can see two scores for the same doc. I have never seen this earlier in solr. What is the possible explanation here. Thank!
