I understand the MLT API to just be a combination of the Get API and MLT
query. The fields specified in 'mlt_fields' are used for both text
extraction to input into 'like_text' in the MLT query and also what fields
to compare against in the MLT query. My question is, is this correct and if
so, is all text placed in like_text (even if fields specified result in
hundreds of words)?

What you are describing is correct. The mlt_fields is used get the fields
and their associated values from the mlt document and create a mlt query.
For each field value combination (for example each array element in a
field) a more_like_this_field is created and the complete field value is
put in the like_text of that query. All the more_like_this_field
queries are combined in one bool query.
