If I beat games I just bought, does it count as a backlog?

So, the steam’s summer sale was here, and even though my library is massive I’ve still bought a few games.

The games I bought:
Super lucky’s tale + New super lucky’s tale
Stray
Lego city: Undercover
Puyo puyo Tetris battle
Horizon: Zero Dawn.

I'm a cat!

I've been eyeing this game since release and finally decided to buy it in the sale. 'Only' 20% off, but definately worth the price tag, even though it's short.

You play as a cat, what starts out really cute turns into a post apocalyptic world.
There's some platforming, but it's mainly a puzzle game where you have to find stuff in order to do/unlock more stuff.

Super Lucky's Tale

A friend and me where looking for games to play as couch co-op on de Switch, after beating Yoshi's crafted world together.
So, we ended up downloading the demo of New super lucky's tale, even though it wasn't co-op.

I immediately fell in love with the whimsical artstyle and the music.
So, instead of buying it on the switch I bought it during the steam sale, because it got bundled with the previous game.

Its a cute little platformer. I do believe the requirement of clovers for a few boss battles was a bit high but I used the dlc clover's to finish it.
All in all it was a fun little game.

Immediately started new super luckys tale right after, but levels are to similar/the same so its on hold.
