Yes, since what is an increment to you (i++) is actually a set to the cache (e.g., set i = blah) where blah has been pre-calculated based on an old value read.  So even if you have R_C, even though your tx is re-reading the field at the time of setting, your application is not.

Basically, with R_C, the 2 TXs would be doing this:

i = 10
tx1: set i to 11
tx2: set i to 11 (even though i already is 11)
