The game has a system that disconnects you if you move too large a distance in too short a time, probably to stop people from cheating and teleporting everywhere. If they only disconnect after using Icarus, that means they dashed to someone that used a movement ability away, which widens the gap enough to trigger the auto-disconnect.
If this isn't the case, then they might be intentionally throwing(or their internet is bad that day).
