When there is 0.7V across the BE junction of the PNP, it is conducting, but that might mean that it is conducting nanoamps or microamps of current. We can essentially say that, in the limit, it is "ON" but that it just happens to be conducting zero current. That happens when Vbe = 0.7V and since there is zero collector current then there is zero base current and, hence, no voltage across the 5kΩ base resistor. So the 22Ω resistor has 0.7V across it and is conducting 31.4mA. Now, as soon as the transistor starts conducting anything more than zero current, there will be some base current which will result in more voltage across the 22Ω resistor and, hence, more current through it.
