There are two forms of APPLY: CROSS APPLY and OUTER APPLY. CROSS APPLY returns only rows from the outer table that produce a result set from the table-valued function. OUTER APPLY returns both rows that produce a result set, and rows that do not, with NULL values in the columns produced by the table-valued function

Basically, the key point here is a table-valued function. since joining table-valued function cant be done with JOIN, then CROSS APPLY/OUTER APPLY is used. This question would have been more confusing if there was OUTER APPLY included
