This ^^ sounds like a pretty logical explanation... Also notice that if you are cruising then move into neutral, when the snychro rev match kicks in (immediately), that it holds the revs for a long time before realizing that you are not moving into another gear (due to coasting in neutral) and then slowly allows itself to wind down. Thus, if you were to downshift and not manully get back on the gas, the synchro rev match is still electronically holding the throttle open for about 3 seconds or so. Because of this, any engine braking would be minimal, if any during that time period. One way to test would be to disable the syncro-rev match and try it again- you would engine brake much harder then.
