Correctible Error

[splitveer]

A1 is incorrectly given 1 free throw instead of 2. When A1 misses the first, A2 rebounds and is fouled in the act of shooting. It is then discovered that A1 should have shot 1 more free throw. How do we resume? Common sense tells me have A1 shoot the un-awarded free throw with the lane cleared, then bring everyone in for A2's 2 free throws. However, the rule seems to state that the foul on A2 would count, but play is resumed at A1's 2nd attempt. Am I reading this rule correctly?

If an error is corrected, play shall be resumed from the point of interruption to rectify the error, unless it involves awarding a *merited free throw(s) and there has been no change of team possession since the error was made, in which case play shall resume as after any free-throw attempt(s).
