Although, jumping nine feet doesn't mean you can't clear the pit... it just means you'd likely need to make a Dexterity check to catch the ledge on the other side. Nine feet is more than enough to get you within arm's reach, and since you chose to jump, you can be ready to catch the edge.
Yeah. This is probably how I would see/judge it. If what I've read about the rules (here) thus far is accurate, then the 9 foot jump for the Str. 9 cleric is a "gimme", then a Dex. check to grab/reach the other side and pull yourself up...or be helped up by someone else (though I don't believe in this particular instance, there was anyone there to help him).
Ye olde skool advice: Never try to leap a pit without a rope around your waist...and, because yes sometimes it needs saying, with someone HOLDING the other end of the rope!
[I still chuckle about the time, ages ago, when my highly experienced group did their "standard dungeon tricks" all of the time. They came to a pit (or a chasm or something, I don't entirely recall), someone tied a rope around their waist and jumped.
When I said "Who's holding the line?" I received a room full of experienced players looking dumbly at each other and then at me in panic, as everyone had already stated other actions/doing other things. Down the shoot the PC went.
I think someone made a diving/grabbing Dex check...followed by a strength check, to grab the end of the rope before it went all the way over the edge (and not be pulled in themselves). But still, was a funny moment. hahaha.]
