Counting clicks (KwikPen) — why do the first 2 clicks “not count”?

Anyone know why some tutorials tell u to click twice on the Zepbound KwikPen before starting to count the dose?

They literally say “these first two clicks don’t count” and then start counting after that. It doesn’t look like regular priming, so I’m confused what those clicks are actually doing.

Is it just taking up slack in the pen or something?

Curious what everyone else does—do you start counting right away or skip those first couple clicks?
