Great pics! Thanks Manu 
I think you got it right about what happened. If the initial seed was collected from E. glaucescens (so labelled as that), that original parent tree was very probably pollinated with some E. perriniana pollen also. So you got at least 1 hybrid seed among the ones in that seed lot.
So, your first tree is the F1 of that original tree. But it is not your F1. Your F1 is its progeny, which you also planted and "reverted" to E. glaucescens. That one is, at once, the F2 of the original tree.
Which means there is some "perriniana blood" in your strain Maybe some of the great-grandsons of the original tree (so, the grand-sons of your first one, or your future F2) show it up again
Problem with this all... the % of runts and strange things will become higher with each generation if it is all done from isolated trees. Not to mention seed outputs tend to be low, because eucs normally have a mechanism to promote cross-pollination, and not selfing.
Cheers
