shroud - Minimap Bug

I was watching VCT then came across this thought. So in VCT your team can ban at least 1 map. You also get to pick your own. I think the banning goes first so your pick might be not be your best map. Unless the opponent bans their worst map...

I still don't understand how the blue outline works if the enemy Yoru uses his ultimate. Does it appear only when he's looking at you (if yes, from any distance?) or if he's close at a certain range?
