After nursing, my baby starts straining and spits up his milk—is the pressure from trying to poop making him vomit?

Yes, this usually happens exactly as you describe. When your baby strains, his belly pressure increases, which pushes stomach milk upward. Especially in newborns and early months, the muscle between the stomach and food pipe (lower esophageal sphincter) isn't fully developed, so this pressure forces milk back up.
This is called regurgitation (physiologic spit-up) and happens occasionally in many babies. If your baby doesn't seem bothered, his weight gain is normal, and the spit-up isn't projectile, there's usually nothing to worry about.
Keeping him upright for 15–20 minutes after feeding, helping him burp thoroughly, and doing gentle "bicycle" leg movements when he strains can ease his belly and reduce spit-up. But if he spits up forcefully after every feed, seems uncomfortable, or isn't gaining weight well, definitely talk to your pediatrician.
