I don't think it's that at all. Truly. I think it's a trust thing of the opposite sort: people don't trust themselves to comfortably (and actively) forget non-critical tasks, which is what the OP does with this method. I think lots of folks keep things in their inbox because of two reasons: 1) removing them feels like loss, and increases risk of ultimate forget, and 2) you can't effectively set a reminder for something you haven't actually read and understood, and most people don't even read the majority of the mail they receive.

On number 2, that's not entirely true, you can be like "I'm not reading this now, I'll snooze it until x when I'll go through some emails"

For me it's all about reducing noise level and cognitive load. It's made me a lot more organised, although occasionally I keep pushing things back and won't admit that I'm not going to do them because I feel like I should do it today but I probably ultimately won't. Curse my fallible humanity!

The "snooze hell" is extremily unproductive if you ask me. Quite often I end up creating an avalanche of reminders just by snoozing/deferring individual tasks until "later" instead of deciding when/where to actually perform the task, so I can continue focus with whatever feels more inportant at the moment...

Oh, brain :-(

I've found "If you can do it in less than 30 minutes, just do it now" to be very helpful in avoiding that
