ASKWB

… if the date of entitlement falls during 1st July to 1st January, the employee after having the benefit of one additional increment, on the date of entitlement, will get annual increment on the next 1st July, but if the date of entitlement falls during 2nd January to 30th June, the employee after having the benefit of one additional increment, will not be entitled to the annual increment on 1st July of the same year; he/she will,however, get the annual increment on the 1st July of the next year.

I like to say in this cases opted 1st July 1 normal increment +1 promotional increment . if non functional promotion.
