Is this ok for sanitizing bottles?

So a month or so ago i wanted to bottle a few six packs off of my keg. At the time, since i was in wash and santize mode, i prepared extra bottles for future use. For the extra bottles, i sanitized a bunch of bottle caps, emptied the sanitize from the bottle, and capped them. Thinking that when i need them in the future, i can just pop the cap, sanitize the bottle top due to contact with the beer opener, and then fill. I went to grab a few of these "extra" bottles and i noticed that they were not properly dried, so there is a little sanitizer on the bottom.

I guess my question is... do you think these bottles are properly sanitized, or did i just waste my time? Can i proceed as planned, or should i resanitize? I guess, if anything, they are cleaned and ready

The bottles are fine. They are still sanitary.

Yes ↑↑
