Correctable error

[som44]

Saw this last night in a HS varsity game after I did the JV game--A1 fouled and awarded 2 shots-time out by team A--after time out administering official indictes 1 shot (not noticed by non-admisistering official) A misses shot B1 gets rebound and begins up court-official immediately blows whistle and corrects error--They let both teams line up for 2nd shot and just played on--My question--should they have cleared lane for 2nd shot and then given team B the ball at point of interuption--ie does the fact that team B got the rebound after the 1st shot imply a change of possession
