The difference between LWE_B[0] and LWE_B[1] of enhanced local bus controller

As described in P2020RM about enhanced local bus controller (eLBC):
Two byte-write-enable signals (LWE_B[0:1]). Asserted/Negated-For GPCM operation, LWE_B[ 0:1] assert for each byte lane enabled for writing.
So my question is:

Whether only LWE_B[ 0 ] is valid when only writing low 8-bit data, only LWE_B[ 1 ] is valid when only writing high 8-bit data and LWE_B[0:1] are both valid when writing 16-bit data?
