Yup, this is why when I draw a schematic I use a little half loop to indicate NO CONNECTION, as well as a dot to indicate CONNECTION. Yes, it is a tiny bit slower, and is a "belt and suspenders" approach, but it makes things absolutely clear. In all my years of working in the electronics field, nobody ever complained about my schematics because of that. I learned this method in the first electronics book I ever bought, The Complete Radio Book by Yates and Pacent (1922).

This is where I first learned to read and draw schematics, and learned the names of the various parts. It is why I still call a condenser a "condenser" and not a "capacitor."
