Its difficult to tell from the photograph.

Is it obvious this has always been one tree, or could it be possible
that branch has been grafted onto the trunk ?

It does look like a graft.

Some trees are grafted onto a drawf rootstock. This allows you to
have a tree with attractive foliage, or plenty of fruit, or
attractive flowers, but which won't grow 50ft tall or whatever
as it would otherwise.

In this case, it's more likely to have been done as the easiest way to
propagate a particular variety.
