is next correct: because datalayer not persistent not have access items pushed datalayer using addtocart event. in order send of products along purchase event need supply products 1 time again part of purchase event.

appreciate help. give thanks you!

adding/removing items shopping cart different action event checkout (purchase) event , there no persistency between them.

so yes, need re-gather products when firing purchase event.
