The guy says he has anterior pelvic tilt / hyperlordosis, i.e. accentuated extenion of the lumbar spine... and your recommendation is more extension?
This is why I don't come to message boards for medical advice.
The iliopsoas is mainly a hip flexor and weak lateral rotator, and shortening will result in pulling the iliac bone anterior-inferior, increasing the lumbosacral angle and increasing lumbar lordosis.

Not a doctor here either....
That being said, from the little bit of anatomy I have learned, the suggestion makes sense. Usually Frequently that tilt come not from tight erector spinae (they aren't really powerful muscles those) but rather from overly tight illio-psoas. (sp?). Back bridges can stretch out the illio-psoas, reducing that pelvic tilt.
It's one of the reasons you see a lot of muscled up gym rats with major low back issues. Too much "ab-work", especially old-fashioned sit-ups or leg lifts instead of crunches or other more pure abdominal exercises. The muscles that lift the legs tighten up and then when you are standing, so your legs are anchored and can't be lifted, the illio-psoas ends up just pulling your lumbar vertebrae downwards towards the legs, creating that anterior pelvic tilt.
So the recommendation is not about getting more extension to the lumbar area. It's about stretching out the muscles connecting the inner thigh to the lower back.
