12.1.3 and RPC2 post install questions

We have applied RPC2 to 12.1.3

The post steps for AP indicates the following:

Refer to document 1341317.1

This document mentions that the Mass Additions performance issue is fixed with apmassab.pls 120.22.12010000.28 and PART II)  to install patch 11868928:R12.AP.B

.

We checked after RPC2 and we do not have patch 11868928 installed .. but the apmassab.pls is 120.22.12010000.49 which is higher than .28

.

So do we still need to apply this AP 11868928 patch after RPC2 to fix the Mass Additions issue ?

Thanks
