Decaf doesn't trigger LES discomfort compared to caffeinated

Side note: I don't have GERD or LPS officially, but I've dealt with some lingering globus sensation and occasional reflux after a gastritis episode a couple of months ago, especially when running or working out. For the last 7 or so years I've had HEAVY caffeine consumption in the form of coffee nearly every day.

A couple of days ago I gave up caffeinated coffee in order to try and relieve and strengthen my LES so I can try and go back to it without the symptoms, but I noticed that after trying decaf, it actually doesn't give me any of the symptoms...

I'm confused, because I've read on here from a ton of people that coffee in general would be a no-go, but does it differ person to person? Is there anyone here in a similar situation where decaf doesn't affect them at all?
