Risp is overcomplicating it. Teleportation means you magically disappear and appear somewhere else and kill people. The fact that teleportation TECHNICALLY works by giving him infinite movement and the ability to go through walls/map sides is not important, since the fully-surrounded thing is likey to never happen and if it does he'll probably get clobbered anyway. Though personally I think "surrounded on all 8 sides by people" is fairly self-explanatory.
