transistors - Why are the current directions in the hybrid-$pi$ model for BJT the same for both NPN and PNP?

Here is the hybrid-$\pi$ model:

with $I_c$ and $I_b$ going in, and $I_e$ going out. The same circuit can be used for both NPN and PNP, the only thing changing being $V_{be}$ for NPN and $V_{eb}$ for PNP.

The currents direction does not change, which is what I don't understand. We know that for a PNP in active mode, $i_c = i_e+i_b$.

For a NPN in active mode, $i_e = i_b+i_c$, which corresponds to the current flow shown on the hybrid-$\pi$ model.

Why is it the same for PNP?
