I don't dispute that. But increasing the primary current will *not* increase
flux density and therefore will *not* take the transfomrer into saturation.
Flux density is unrelated to current.

Once you get past the level of the magnetising current I think you'll find one
transformer will have an increased primary current and the other will have
exactly the same level of primary current but it will be acting as a source
back into the grid.
