Yes, I see that variation now - you are talking about this track, correct? https://www.openstreetmap.org/way/1389544922

This one was previously not even mapped! So I added it and mapped 605 on this new track as per my colleague's gpx and this description where it clearly says to go RIGHT (and later pass by the cottage/hut), not left: https://www.hike.uno/view_tour/malborghetto_cima_alta_due_pizzi_path_605/560300

From the picture itself, it seems that there is indeed a marking on the right tree if you look closely. Implying that this track would be the correct way: https://www.openstreetmap.org/way/1389544922

But do check with CAI if possible and we can correct if needed.
