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.
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.
