I *am* protecting the shooter all the way down, but not from all contact.

In this particular quote the word forcefully is used to specify that this is not only a foul, but can in this circumstance ("clean block" up top) be called intentional if the contact is excessive. Following this line of reasoning, any (illegal) contact which (gently?) knocks the airborne shooter to the floor will usually be regarded as a foul.
