That's pretty much it, yeah. I'd just add: the loop is technically a bug that Bethesda never patched, so it sits in this weird space where it's not cheating-cheating (like console commands), but it's also not how the game's meant to work. Some people are into that, some aren't.
The thing that gets lost in the hype is that Restoration as a skill tree is already pretty good if you just... play normally. The perk that boosts healing spell effectiveness stacks naturally, you get perks that make spells cheaper, and by mid-game you're healing through anything that doesn't one-shot you anyway. There's no endgame content that demands you have perfect healing optimization.
Where I'd maybe push back on the "just flexing" take: if you're on a harder difficulty or running survival mode on SE, knowing the loop exists is useful knowledge even if you don't use it. Like, it's there if you hit a wall. But that's different from feeling like you have to do it.
At 22, just keep playing. You'll naturally figure out what you need as you level up. If you hit a point around level 40-50 where you're like "man, I wish my healing was better," then you can look back and decide if it's worth messing with. Spoiler: it probably won't be.
