Is Cubase tempo detection kinda bad, or am I using it wrong?

So basically you’re saying that if I follow these steps, then the files should basically have the perfect tempo, so I should see some peaks aligned to bars and all that, kind of like when I do it with Logic Pro X. But it doesn’t seem to be the case. I actually duplicated the file twice, and opened each file in iZotope RX10 to trim the parts.

Then I started two separate Cubase projects, one after the other, and did the tempo detection, set definition, write to file, and then started a third project, brought the first file, then the second one, and to me the bars still don’t align to the waveform like they normally do in Logic.

Maybe this guy played totally out of tempo going up and down, but at least to my ears it’s not some craziness that slows down and speeds up all the time, it sounds like a pretty normal rhythm guitar.
