If that's true then it makes sense.
As the "plot" goes:

OoT ends (3 way timeline occurs)
Young Link is sent back after saving Hyrule
Young Link ends up in Termina
Young Link saves Termina
However, isn't seen from again as it's "known/theory" that Young Link; after finishing his journey, get lost in the Lost Woods.
As the "legend(within the game)" goes, anyone lost in the Lost Woods becomes a Stalfos.

So I guess that would explain why he is a Stalfos but not necessary a bad one and would also explain how it is Young Link from OoT/MM.
