Somewhere in the cutscenes and dialogue one of the main BLU NPCs says something about "... how you are learning it from them and the more you watch their actions the more you shall learn..." implying that you need to be facing the mob (looking at it) when the target does the ability you want to learn. Also the faster you kill it after it performs the ability affects the % of learning it too.
. I know you can still learn it other way by facing askew, but I remember reading in the Q&A they had very early on that the dev team replied that the rate of learning the spell, if you're not facing the target, dropped drastically, and the longer you wait to kill it lowered the learning rate, too.
. Hope that helped even a tiny bit, because they can be a P.I.T.A. to learn.
