That would consider the angle of the rocket, if its too high it would be considered impossible because you cannot jump over the rocket launcher itself to pass the phase, aka you making the jump too close to the host, but if its on the low angle you could jump over the rocket to pass the phase, and the jump has to be away from the host.
We can work on making this rule more clearer to make it easier to understand however the timing of your jump for Round 4 looked to me that you jumped over the host's shotgun which was going above the host, so we may add a rule to determine adequate distance from the host for jumping. However as it is now, from my view it looks like a rule break by the current ruleset.
