The term in that Floyd track is not a hard square wave. It's a bit rounded. Adjust my preset with attack and release on the modifier.
Still it sounds different than what you get out of the volume block with the sequencer and envelope attached. Somehow it sounds less focused and rhythmic. Hard to describe.
I tried your LFO trick and used a square wave and that gave better results. So thank you for that!!
