My read of the final two pages is that the cut from one to the other was literally the kind of subtext that comics can do.
It looks at first glance like the two of them are just about to encounter each other—that if the chapter went on for a page or two more they’d run into each other on the street.
But, as @shojie07 says, the different lighting suggests that the two scenes are not quite simultaneous—broad daylight for Yuu, early evening for Touko.
But staging potential suggests that their meeting won’t be on the street but in the student council room Where It All Began. Still, Nakatani is a quite structural writer, but also subtle enough to maybe first foreshadow a stuco room meeting only to have them meet earlier.
But I suspect not, and so the running-toward-each-other-but-not-quite feel of that faux-crosscut will end up with us all back in the Tabernacle of Love/Not-Love Student Council Room for the big showdown.
