If someone shows you this expression, you shouldn't pick an interpretation, you should slap them in the face and tell them to write unambiguous expressions. The very fact that this discussion exists is evidence enough that this is a terrible way of writing whatever it is supposed to mean, especially as there completely non-ambiguous ways of writing both possible interpretations.

I'm a graduate student in theoretical physics, so I have a fair share of mathematical experience too.
