comment When is the induced representation factored through the initial one?
When $H$ is normal, then $\rho\circ \iota$ is a bunch of copies of $\pi$, so there the desired factoring is true.

comment Jordan-Holder vs Harder-Narasimhan
I know of at least one source that uses "Loewy series" for any series with semi-simple quotients of this length. Also, this is the dual of what Wikipedia calls "Loewy series" en.wikipedia.org/wiki/Loewy_ring
