New Correctable Error?

[iref4him]

In the 2008-09 High School Basketball Rules Simple & Illustrated, Page 25, the bottom illustration, says

3-3-3 Number 4 runs onto the court without being beckoned by an official, while the ball is live. The penalty for this infraction is a technical foul. If the official fails to detect the illegal entry and it is detected by the scorer, he or she may call it to the official's attention. When this error occurs and it is not immediately penalized, it may be corrected, provided it is recognized before the ball becomes live following the first dead ball after the infraction occured.


I thought it would be to late to penalize, since Number 4 already became a player. Also, I did not see this as a correctable error.

Any thoughts???
