Are the hyenas magic?

Well, I had a lion king marathon the other day, (going 1, 1/2, 2), and I noticed that during the lion king 1, in the final battle, you see Scar telling Simba it was the hyenas fault. The hyenas (Shenzi, Banzai, and Ed), hear this and back off.
During TLK 1/2, They chase Timon and Pumbaa after Simba spots Scar running off. After the hyenas fall into the hole Timon makes, Scar falls off the edge of Pride Rock. Like 2 seconds later!
So, the hyenas couldn't of heard Scar say it was their fault, so they'd have no reason to attack!
This timing is all wrong. This is impossible unless Shenzi, Banzai, and Ed have identical twins!
I suppose this is yet another Disney mistake, but it's a huge one!
