Yes it is, if my ideas are the right ones :-)

Yes it is, if you have an 'off by one' error in the transcode, it fails.

No it isn't. AFAIK, AMA relinks (partially) based on clip duration. (at
least 5.0x)
AMA clips do not have a Reelname, they have pathname and clipname.
Not sure how it relates to 'normal' (also cumbersome) relinking, but it's
different.

This confuses me, as it is really different from my experience...
What version are you on? And, Win or Mac? (god knows if that's a
difference...)
