the clips do not demonstrate anything new, they are merely a collection of e examples of how you should be determining offside..
for the last few seasons
I'm sorry but I have to disagree. This is, as
@cwyeary mentioned, a substantial change in how we're supposed to judge a deliberate play.
Just consider the following wording from this "clarification":
‘Deliberate play’ is when a player has control of the ball with the possibility of:
passing the ball to a team-mate; or
gaining possession of the ball; or
clearing the ball (e.g. by kicking or heading it).
(Emphasis mine).
For many years now, there has been no hint of the player having to have actual control of the ball, for it to be considered a deliberate play.
The part about having the possibility to pass, gain possession of, or clear the ball is also brand new.
Previously, so long as the player made contact with the ball in any way that looked like they intended to play the ball, that was considered a deliberate play. Whether the player established control of the ball or ended up with the possibility of doing something useful with it, was wholly irrelevant.
As others have said, there were a large number of incidents in recent seasons where the ball skimmed off the head or leg of a defender who was never remotely close to controlling the ball, gaining possession, passing or clearing it and that was considered a deliberate play. Examples have been given above.
Now, virtually all of those incidents, if they occurred in the coming season(s) would result in an offside call.
For me, this is a major change and the IFAB trying to disguise it as a mere clarification is somewhat disingenuous.
