Under what circumstances will Utf8JsonReader.HasValueSequence be true?

I have begun working with raw value spans and sequences inside my JSON converters. I noticed that Utf8JsonReader provides a property to check to see whether the value is a sequence: HasValueSequence. When will this be set to true? I noticed that JsonDocument accepts a ReadOnlySequence<byte>, but I am mostly interested in the context of ASP.NET Core. I tried sending a 10MB JSON value to my endpoint, and it still was not a sequence.

2020-11-30T02:03:37.127+00:00 I don't have a
JsonDocument. I specifically mentioned ASP.NET Core as the context. TheUtf8JsonReaderonly comes into play when triggering my customer serializers. I'm asking if/when ASP.NET Core opts to make it a sequence instead of single span.
