If the same product is associated with two courses, can users access the un-purchased course for free?

When the same course is associated with two paid columns and a user only purchases one of the columns:

1. If the associated course allows individual sales, the course can be viewed in both columns. However, if the column that the user hasn't purchased doesn't display the column catalog, the course cannot be viewed.

2. If the associated course doesn't allow individual sales, in the column that the user hasn't purchased, a prompt 'You can watch this course after subscribing to the column' will appear.
