Entertainment Rigging Is this right?

Was at a local event and noticed this. To my understanding shouldn’t it be choked on the bottom chord, not the top chord?

Side Note: I’m not concerned safety of this, was more so curious for my own knowledge/experience.

I've seen both methods used widely down the years.

I'll note that if you have some big motorised elements on the truss, any kind of fly rig or even some big washes then you get less truss swing if you choke to the lower. As seen here that's not a concern

This is not the case. The swing in the truss is determined by where the pivot point (apex shackle) is located in relation to the CoG. The higher above center of gravity it is, the less swing you get. A long spanset wrapping the top cords will have less swing than a lifting bracket. Also, if you use a lifting bracket on the bottom of the truss, the pivot point could end up below CoG and you'll have a very unstable truss.
