Question about indexing linestring without distance_error_pct

[whiteonyx_go]

Hi

Indexing LineString without specifying precision or distance_error_pct only hit the query at the start of LineString.
If precision is specified, distance_error_pct is implicitly treated as 0, so I think that distance_error_pct is actually involved.
Is this behavior as expected?
I couldn't understand this behavior by looking at the documentation, so I asked a question.

Geo-shape field type | Elasticsearch Guide [7.12] | Elastic

A Schema is like this.

• only hit start point of LineString

{
    "properties": {
        "line": {
            "type": "geo_shape"
        }
    }
}

• hit all point of linestring(query return results expected)

{
    "properties": {
        "line": {
            "type": "geo_shape",
            "distance_error_pct": 0
        }
    }
}
