AFAIU, it is because there is no common way to call a function after
ending a completing-read and/or completion-in-region call so we end up
needing a UI specific way to do so.  The function records the selected
candidate, necessary for fuzzy(?) matching based on frequency and
recency ("frecency").
The README does a better job at explaining this than I do here (which is
based on understanding on how the package worked before it underwent
extensive rewrite).
