911	AMVP process might overwrite candidate A	pieterkapsenberg	bbross	"In 8.5.3.1.6 -	Derivation process for motion vector predictor candidates, step 4 of the derivation of motion vector mvLXB and the availability flag availableFlagLXB reads as follows:

4. When isScaledFlagLX is equal to 0 and availableFlagLXB is equal to 1, availableFlagLXA is set equal to 1 and the following assignments are made.[[BR]]mvLXA = mvLXB[[BR]]refIdxA = refIdxLXB

Shouldn't this step be conditional on availableFlagLXA being 0 initially? Otherwise possibly the already-added A candidate will get overwritten. The code in HM-9 does not appear to allow replacing an added candidate.
