In-play delay - Match Odds ( Soccer )

[lmigueltavares]

Wolves vs Man City (in-play delay 7secs)
If the in-play delay is 7 secs what is the reason why after a suspension there is cash traded as soon as one second when the minimum time in this game is 7 secs.
Has anyone noticed this situation that happened in almost every game?

People at the ground will do something in anticipation of it happening in the hope of beating the delay.
