Question about powerpass and alts

Hello guys I’ve not long since started playing this game

I just leveled my main arrived at vern and received the powerpass

Used it on an alt but the thing is it seemed to boost my alt past my main with the questing thats what I’m confused about

Now my main has to run all the adventure quests etc and main to catch up to rohenal

Is that just the way it is

Is there not way to use the now further ahead alt to boost up the main

It just seems silly to me that’s all

Thanks

Knowledge transfer would that work on my alt to bring my main up to rohenal?
