It does make it more likely to be true when it's the perception of the majority. Certainly seemed to effect the game, last time I played it was dead. I played against the same Tau player several times, switched to Orks to see if getting up close would work because trying to kite with Chaos wasn't really, but I ended up just sitting in que for idr how long until I just quit and haven't come back yet. You say it was just a bug, but it looked like OP shit to me and we can't confirm the timeframe. What I do know is that supposedly Tau are supposed to excel at what 6 to 9k range? You know, where basically the whole fight takes place.
