accidental offside touch

Aren't both examples of IFAB Law 11, "interfering with play by playing or touching a ball passed or touched by a team-mate"? That is, both appear to be an offside offense.

The law doesn't specify whether the touch was intentional or not. And in case (1), it is speculative to say that that the offside player's touch had almost no effect -- it was a touch that (by virtue of touching it) interfered with the play.

Newbie ref here, so I may be missing some intricacies.
