Logic has such a long history, it's not surprising that it shows it's age, and has 'weird' behaviour that you wouldn't choose today. It's got stuff in there from the early 90s, as it started out as a midi sequencer before pulling audio into the product.
It feels like the audio code was not touched since emagic days.
For making demos and filling-out sketches, I'm thrilled. Here's the audio, and all rough playing, bum notes and general incompetence are my own.

Fun toy, though! I take it you extended it backwards into an intro, or you have playing it can read that you muted, leading into your guitar stuff. Did you play to a click or is it reading your tempo too?
Every other modern DAW does this automatically. In Logic, you are expected to do this manually every time you do an audio edit. Like it's 2004 again.
Edit: added clarification about zero crossings and editing workflow
