# Self-induction and induced currents

I was reading the chapter about self-induction and inductance from "Physics for scientists and Engineers with Modern Physics, vol. 2, Eight edition - Serway | Jewett" and I can't understand the last sentence of the following quote:

Consider a circuit consisting of a switch, a resistor, and a source of emf. When the switch is thrown to its closed position, the current does not immediately jump from zero to its maximum value e/R. Faraday’s law of electromagnetic induction can be used to describe this effect as follows. As the current increases with time, the magnetic flux through the circuit loop due to this current also increases with time. This increasing flux creates an induced emf in the circuit. The direction of the induced emf is such that it would cause an induced current in the loop (if the loop did not already carry a current), which would establish a magnetic field opposing the change in the original magnetic field.

Why does it say "it would cause an induced current in the loop, if the loop did not already carry a current"? What is the reason of using the conditional form?

I thought that an induced emf generates an induced current (which won't be the same as the one generated from the physical source, indeed), so I'm quite confused about this paragraph.
