No, this is you jump so the game says you're further away than you actually are. Lets say jump moves you 1 yalm up and max attack range is 5 yalms. If you're 5 yalms away from someone attacking you and you jump, you're suddenly out of range because the distance between you and the person trying to punch you is now 5.099 yalms. That's .099 yalms too farm! No attack for your enemy they just get a target out of range message.
