The same product under the industry's own name, with the arithmetic attached.
The industry's own name for it
Welcome bonus is what operators call the offer; signup bonus is what people search for. The product is identical, and so is the way to price it.

The same multiple, two different offers. When the requirement applies to deposit and bonus together it is exactly twice the play, and that line sits in the terms rather than in the banner.
Where welcome offers differ from the rest
They are the largest offers a casino runs and the ones with the steepest terms, for the same reason: they are paid for by the accounts that never clear them. A reload bonus has to be worth taking or nobody takes it. A welcome bonus has to look worth taking, which is a different design problem.
