The other possible BIB is as the offensive player is running down the sideline a few blockers come in and w/o the best field position and one appears to push the defense to the sideline.

Ray, it makes no difference where the blockers helmet is. This is a common misconception that should not be a determining factor. Now, if the head is in front, I'd say it is probably impossible for a block to be a BIB, but it is not one just cuz the head is behind the side.

2-5-2 Blocking in the back is a block against an opponent when the initial contact is in the opponent’s back, inside the shoulders and below the helmet and above the waist, and not against a player who is a runner or pretending to be a runner.

The block at the .06 mark IMO is legal cuz it is from the side and is not inside the shoulders. Another good thing to help determine if a potential block is a BIB is how the player falls. If the contact is in the "back" the player will often fall on his stomach. Now, not always but it can be a helpful factor in making the call. In the block at .06, the player falls on his left side, which could help indicate the block was on the right side, not in the back.
