Why does "Export As" have a "Select All" checkbox if it is IMPOSSIBLE to list more than one image?

Question

I have 25 images that I need export using the control of the Export As dialog box. I need to set the Quality, Image Size in Pixels, select the Reseample option, remove the Metadata, and convert the color space to sRGB. When I open all the images in Photoshop 2025 and then select File / Export /Export As... I am presented with a dialog box where one of the optional checkboxes is "Select All" with the one image that I have active in what looks like it could be a list, but is currently a "list" of one, and it is checked.
Why have the "Select All" checkbox if it can only provide the option of checking or unchecking the ONLY image in the list? Very confusing...

As @Srishti Bali has replied, Export As isn't intended for batch processing multiple documents. You could use the built-in script "Load Files Into Stack” and then Image > Reveal All if required, and then run Export As to output all layers... But that’s a bit of a pain.

Photoshop offers batch processing of separate files via batch actions and droplets, however, I prefer scripts.
