That's the way I read it, but the narrative is pretty vague. That same thing (sort of) did happen with my first real job. When they ordered me they also let me know of an opening for a slightly different position that better matched what I wanted and actually took. I think for tech work, HR folks don't necessarily know what you do or are qualified for so it would be good to have a promising candidate apply for any other positions they may be interested in.
My company does a big hiring process (or used to) where they would bring in 60-80 applicants for two days of interviews, case studies, presentations, and social gatherings. On the second day, you would fill out a sheet with your top three position choices, although I don't recall ever even seeing job descriptions for those positions. You may never interview with the hiring manager for that position either. At the end of the whole thing, about a week later you would potentially get an offer after the different people rated you and recommended a fit to a position depending on your skills.
The whole process was amazing and the people that my company hired through it usually had a much better washout rate than many in the industry.
