You interpreted this correctly. At the Q&A after the premier James Langford commented on this and thanked Director Jamie Winterstern on his tasteful nod to Samaras and Jamie thanked him for noticing that. I am amazed by how much effort Jamie put into learning about chasing and the chasing community. In just a couple years he learned a lot and he picked up on a lot of the nuances that many new chasers these days never seem to pick up on. He still chases even though the movie is done.interpreted the death of Bill Brody Sr. as alluding to the death of Tim Samaras and the TWISTEX crew in 2013
A few other interesting things about this movie: the story the Roy Cameron charter tells about the check on the dining room being the only thing that survives a tornado is a story that a clerk at a gas station in Shamrock told Jamie when he was chasing in real life. Another fun fact - the name "Brody" is an easter egg. It is a nod to Spielberg. Police Chief Martin Brody is the fictional character and the protagonist in Jaws.
