Yep, not the norm. But I'm left-handed, and used to doing things the wrong way . Regardless, it's how an old friend who got me into serious cycling some 30 years ago set me up. It's the only way I've done it since. I pull out on the strap more than up. I dunno, maybe they held better for him. Release is dead easy. Stay with whatever way works for you though!

AFA pulling up, I pull back moreso than up.

And rootboy, I can't see the clips and straps for the distraction of an obviously NOS NR crankset.
