Yes, he can get both normal & promotional increments simultaneously on 1st July if he opts for that. In that case he will get ONLY the promotional Grade Pay with effect from the date of promotion, and get both the increments on 01.07.2013. However, if he wants he can get promotional increment from the date of promotion in February,2013, but in this case, he will not be eligible to get normal increment on 1st July,2013. His normal increment will be deferred to the 1st July,2014 instead. See the clarifications at points 2 & 3 in the F.D. Memo No. 2728-F dtd 07.04.2009.
