[Soulguard] (If this card would leave the field, you may discard one soul to prevent it) What's confusing? Yes, in both instances, the card is still considered destroyed for those effects.but again, the card remains on the field.

Soulguard doesn't react to the destruction of a card. It reacts to when a card would leave the field. That's how it always has worked since Day 1.

For your scenario, in the case a card with Soulgaurd and 1 Soul is destroyed and this card is applied onto it, you have the choice of either A) Using Soulguard or B) Using this to keep it on the field.

Also note that Soulguard is an optional effect. Hence the "may" part of it.
