When the period of extraordinary leave exceeds one month, but does not exceed eleven months after 1st July of usual annual increment, the Government employee may be allowed the next annual increment notionally on the 1st July of the next year. However, the actual benefit of increment will be admissible from the month after deducting the non-qualifying month(s) of service spent on extraordinary leave from the 1st July of notional incremental benefit.
As per this statement of that G.O you are right as fer as my knowledge is concern.
