Ha, yeah, I tend to do that when I'm multi-tasking. I'll usually be on MSN or something, then look down at my DSi and be like "...I didn't hear it. -saves-". I don't think I've ever saved more than 3 times in a row, though.
I do tend to save a LOT though. I've made it a habit to save every single time I go into a Pokemon Center. I also save if something good happens, like a Pokemon levels up, or I hatch a Pokemon... I also save after EVERY EV. Just in case.
I also tend to save right before the Bug Catching Contest, but I almost never reset. The last time I reset was before I got the National Dex. I was trying to catch a Scyther at full HP, but no matter how many balls I threw it wouldn't catch.
I had two balls left... Then it fainted my level 55ish Ledian with a Critical Hit.
I reset, owned a random Scyther, captured a level 18 Weedle and accepted my prize... And Saved. xD
Although, back before I beat the game, I never saved before important battles. To me, that was like cheating. I regretted it during the double battle with your Rival, though. My levels were like... Early 60s. All his Pokemon fainted in 1 hit.
I was like "...Well, this is going to be quite beautiful." and proceeded to spam Revives/Max Revives/Revival Herbs and Hyper Potions/Full Restores. I managed to win, but it was mostly due to some lucky critical hits and item spam.
Then I proceeded to go to the E4, and own Lance's mysteriously de-leveled Pokemon just for the sake of my sanity. >_>
In any case, this is getting pretty off topic... Let's just say I have weird saving habits and be done with it!
