I don't think the comment that he dressed at forward only once for two minutes of ice time is close to being accurate so am going to ask you to provide some sort of source.
Certainly Canucks Army doesn't agree with you. In fact, their comments at times support the narrative that BG has had for some time that the Canucks were actually considering Pedan as a forward.

"Last night, Pedan played another game as a forward with the Canucks and it appears that Coach Wilbrod Desjardins feels that this is a good plan:
#Canucks WD on Pedan: ‘an opportunity to be a versatile guy who can play F & D. Not ruling him out as a d-man, but this is a chance to play’
— Jeff Paterson (@patersonjeff) April 3, 2016
So, with only three more games left, does this ‘opportunity’ continue?
Canucks colour commentator Dave Tomlinson was on TSN 1040 yesterday and said this is a great opportunity for Pedan to ply his trade as a swing player with the Canucks. He made the argument that the alternative is to not play, and thus having Pedan in this role, is a good way to utilize their players and ensure they are game action."

"Former Canucks coach Willie Desjardins played Pedan as a forward in his NHL debut, kicking off an asinine idea that Pedan should be some sort of “swing manâ€, capable of playing both forward and defence. As a result, for roughly half of the 13 NHL games Pedan suited up for that year, he did so out of his natural position, with minimal fourth line minutes. The decision to play Pedan up front was, as my colleague Ryan Biech put it (rather conservatively), misguided at best. Desjardins squandered the opportunity to evaluate one of the team’s best defensive prospects if favour of foolishly experimenting with “swing†players."
And from

"It’s regrettable that Pedan’s 13-game stint with the big club tells us virtually nothing about what he can do as an NHLer. Not only was Pedan playing on garbage time, largely as an experiment, but he was also perplexingly deployed as a forward for much of his time in Vancouver."
So what we had were reports of Pedan improving his defensive work after a good deal of work-including video work-with Green, followed by him getting a chance with the Canucks in which he was deployed much of the time as a forward with the Canucks' coach of the time speculating about him as a forward, during a time in which he won the fastest skater and hardest shot contests on the Canucks. He then was reassigned to Utica and has been inconsistent ever since, to the point where many don't view him as much of a prospect at all any more and the rest view him as pretty much a bust.
I haven't gone through game by game records to determine Pedan's actual ice time and time as a forward, but unless you can produce something to show he was used for "2 minutes" in "one game on an emergency basis" that statement doesn't appear accurate. It appears that not only did the Canucks consider using Pedan as a swing man, they chose to try him in that role before they got some healthy bodies back and reassigned him back to Utica. For whatever reason, his game immediately took a downward turn and hasn't recovered.
It isn't a stretch to think it had something to do with his mind getting diverted from what Green had been teaching him before his callup.
