This may be too nitpicky, but are those passes technically screen passes?
Any forward pass that does not cross the LOS (Line of Scrimmage) is a screen pass.
*Sidenote... Any pass that does not cross the LOS (thrown behind the LOS) allows the Offensive Lineman to release downfield to block before the pass is actually thrown. If the pass is thrown across the LOS, Offensive Lineman cant release down field until the ball has been thrown, as it will result in illegal man downfield.
In the case of the RB screen, OL usually want to pass set first, to invite the DL up the field, before they release to the LBs and Safeties to block. In the case of a WR Screen which are usually thrown far out to the sideline, OL can aggressively run block and release to the LBs, Safeties and sometimes Corners right away (however some OL still pass set to clear the pass rush in the case of the WR middle/tunnel screens, which is the outside WR's running in toward the middle of the field while behind the LOS.
