Seems to me the caveat "unless the alien would be eligible for a full 6 years of authorized admission" may well come into play here. Since the current H1 has been abandoned, its not going to be either a renewal or an extension, so that basically puts you back at the starting block?
Consult an immigration attorney for a more reliable opinion.
Sorry to say this, but you are on your own interpretation, and is not based on what law says.
Do you know what the requirement for full 6 year eligibility ? It is clearly stated in INA and interruption of status is not a part of that.
I really don't understand what "abandoned" mean ? There is no such thing called abandonment of H1. H1 status may get invalidated if you use EAD, but that is only for that particular physical presence in the US. And H1 petition remains valid until it's expired or cancelled by employer.
In either way, you can apply new H1 petition.
This H1 quota rule is very basic and is well known.
We have regular Q&A sessions with Mr. Kanna(You know who he is, right ?).
Somebody asked a question regarding EB GC process in Mar 8 conf call and, along with the same line, the discussion went to 7th year extension ability.
The guy has already exhaused full 6 years and is using EAD for a while. Mr Kanna suggested to get back to H1 and the guy got surprised that he had such an option. Mr Kanna said even though one exhaused 6 years and then used EAD for 2 years, one still can get 7th year extension. There is a little more background why the guy thought 7th year was not possible under such circumstances, but I don't go there as I have to quote a few CIS memos for that. The point is even if you are on H1 6 years and spent some time on EAD, you can still get H1(7th year or beyond) if you are eligible to 7th year.
7th year extension is possible after using EAD, then why not possible to get the remaining period of H1 w/o being subject to quota ?
Being on EAD won't affect your ability to get "extension"(and of course, so called "extension" is exempt from quota).
You can listen to recorded conversation of conf call.

The discussion I referred to is sometime around 15 min to 17 min.
