For those wondering, you see how the rods are alternating diagonal? When the downward part of the bottom rod hits the table, it bounces up, pulling the other side of the rod, and therefore that rope, downwards. Rinse and repeat with every rod, all pulling slightly downwards on the ladder, and now it's falling faster than the other.

Since the rungs are angled, the table is causing them to flatten out, which pulls down on the rung above it. This alternates left to right, gradually speeding it up.
Edit: Never expected my comment to get so much attention. To elaborate a bit, one needs to understand that even the ladder on the right will speed up after it hits the ground, just like the one on the left. The only reason you see the difference is because the one on the left hit the table (higher ground) before the one on the right. Also, to better see the pulling effect, don't just watch the strings close to the table. Look closer to the top of the ladder, like two or three rungs from the top after the top comes into view. You can clearly see motion in the strings that is not seen in the ladder on the right.

@Veritasium I think two things may be contributing to making the left ladder fall faster. 1) Considering that this is not in a vacuum, drag/air resistance could be an important matter to consider. The topmost bar of the rope experiences a cumulative air resistance of the lower bars and some of the ropes below. There is a gradual reduction in cumulative air resistance on the left ladder, while there is no such reduction on the right one. The acceleration on the left ladder increases. 2) Every time each bar on the left ladder reaches the table, the bars being at an angle, the bar that touches the table pivots at their center point creating a pull on the shorter rope which visibly seems like a gradual speeding up of the fall

Plot twist: he has no idea why that happened and he's genuinely asking, hoping that someone tells him in the comment.
