The bleed nipple should be below the hose when attached to
the tranny. Otherwise, you have the opportunity for air above
the line.
It's been reported that they are shipped with the nipple in the
wrong hole. So it's likely you did the right thing.

I think Charles covered that. push it in all the way.

I've given up on a helper to bleed. I really like my ezibleed.
Others like the mitivac.
I think it's Paul Hunt who hooks the ezibleed up to the slave and pushes
fluid up (after he has bleed down to make sure he has clean fluid
top to bottom).
With a Ezibleed, you just have to be sure you don't use too much
pressure. I've been thinking of going to Menards and getting a sprayer
canister, like for deck wash or weed killer and building a little
compressor instead of using the spare tire all the time. I think it just
wants 10-15 psi.
I did my clutch first time when I pulled the engine 3 years ago. I
didn't have the Ezibleed then and my wife did it. It was fine. Last
year, I replaced the hose, because I didn't like the look of it. The
Ezibleed did the job in about 30 seconds.
I still have a bit of squish in the brakes. I've been trying to blame
the power assist, but I don't think that's it after reading the thread
on that. Oh, that thread was on yahoo. I still don't like the look of
my vacuum hose for the power brakes. Is that a regular hose, or do I
need something special?

I'd bet that is the hose.
