Good news for you! "Out" is almost always a sideways movement in most (all?) pedal systems (because that's what's natural and you want to be able to pull on your pedals and not come out).
I still, to this day, pop my planting foot out well before I "have" to stop when given the fair warning, like when I start coasting towards a red light. I'm minimizing that time now, as I'm very comfortable with my pedals (especially on the road), but as a newbie it really helped give me the confidence that it was one less thing I had to worry about and reduced my clipless falls (still none on the road) to "emergency" situations where I had to slam on the brakes. Now though, my reaction times for grabbing fist-fulls of brake and unclipping are basically the same and it has become one fluid, subconscious movement whenever I feel something is going wrong.
O, and when/if you "just eat it" your pedals typically auto release. I had a pretty impressive semi-hydroplane incident a few years ago. Two loud "POP" noises and the bike was free before the pedal hit the ground (freaked my riding buddies (most of whom didn't ride clipless) out; I think they thought the noise was my collarbone!!!)
