I also noticed the snap was high. Many feel Bass issues are mental, but after seeing he missed the XP on the high snap, makes me wonder if it's more technique, that he's just to anxious and needs to wait a split second longer, but instead he gets moving too early. If the snap is perfect, no issues, but if anything is off by just a fraction, then his timing is all off too and he misses them. Maybe he gets too amped up??
