I haven’t snelled a hook in years but I want to on some string leech patterns.
Doing a google it seems there are two ways to do it.
One …the easier one …has the line end going over the wraps…and the other doing loops over the bend of the hook has the line end coming under the loops…
Usually the line is brought through the eye and looped around the trailer hook, without a true snell. Just wrap in a loop on the front hook, which is usually cut off at the bend. I have never seen one tied with a single piece of line and snelled to the rear hook but these are seldom tied for small fish and strength is a serious concern.

The snell knot is tough sometimes, I have one of the Rudy’s snell tyers and it works good. The other option you can use is try a Uni knot for the snell it works pretty close, tie the knot on the hook then run the long end through the eye it makes it easier.
The only way I have ever done it is with the loops going over the the line and hook shank around the hook bend. I think the other way is like a uni-knot connection.
