Section 3.1 says:
A detailed rationale and discussion of the IW setting is provided in [RFC3390].
It should say:
A detailed rationale and discussion of the IW setting is provided in [RFC3390]. The IW value for the case when (SMSS > 1095 bytes) and (SMSS <= 2190 bytes) is changed from RFC3390. The new definition will keep early values of cwnd at a multiple of SMSS and avoid transmitting partial segments.
Hopefully, I surmised the reason for the change correctly.
