The dispute is whether both were drawn at the same time, and came out different because of ink flow effects; or the word was written once, was or became faint, and then was carefully, but not always completely, retraced with dark ink. Is that a good summary of the issue?
Yes, this is a good summary.

I don't see how those symbols could be interpreted as valid glyphs with some parts missing.
The infinity symbol is rare, but still appears a few times in the MS. Probably this is just e and o jammed together. There has been a discussion about these fused symbols, I think it was Dobri who started it. Here's the thread You are not allowed to view links. Register or Login to view. and I'm attaching a sample image of fused characters I made for that thread. So, yes, it's rare, but I don't think it's an invalid character in the sense that by producing it the scribe indicated their lack of knowledge of the script.
As for "reversed "i" with serif", I think there are a lot of base minim/curve variations in the MS, so I'm not sure this symbol is particularly strange, it's just not the most common version. If needed I can try hunting for more examples, I don't have them ready.
