Welcome to the forum.
wait waits for a shell's background processes ("jobs") to finish. None of your scripts is executed in background - unless we're talking of some code part within either, for which it would make more sense to wait within.
When executed in "normal" foreground mode, each script WILL execute the .sas commands in sequence AND exit only when all are finished.
