Here is the guy who put the seal on the toilet first:
He makes several mistakes.
The closet bolts he uses are not tight enough in most cases.
He removes the old wax without wearing gloves. There is a putty knife sitting to the right that should have been used for that. He eventually picks it up and then uses his fingers again. Really?
The wax ring on the bowl can drop in the wrong spot. It's why plumbers don't take that chance.
He doesn't even check to see if the bowl will need shims. BIG Mistake.
He cuts the bolts before flushing to see if the seal is good. Always flush first. The bolts never get cut before checking the seal with a flush.
Plumbing code requires that the bowl is caulked to the floor, leaving the back near the wall open in case the seal fails.
Typical video done by someone that doesn't have to plumb for a living.
Jamie also sings in a band and I do video in addition to plumbing.
