Comment (by smallishzulu):

 Official NVIDIA Reply to this ticket over their ticket system:

 Here's the description of the B-as-reference "each" mode, from the
 EncodeAPI header file:

     NV_ENC_BFRAME_REF_MODE_EACH     = 0x1,          /**< Each B-frame will
 be used for reference. currently not supported for H.264 */

 As indicated, this mode is not supported at all, so the current behaviour
 is correct. When this mode becomes available in the future, the value
 returned on calling NvEncGetEncodeCaps() with the
 NV_ENC_CAPS_SUPPORT_BFRAME_REF_MODE capability will include
 NV_ENC_BFRAME_REF_MODE_EACH.
