No. When "greedy" is set, a RegEx object will look for the longest
possible match. Consider the following example.
Source = "(((foo)))"
Regular Expression = "\(.+\)"
With Greedy = true, the match string will be "(((foo)))". If Greedy
= false, then the match string will be "(((foo)".

No, that's not what Greedy means at all. Greedy affects the way
matching is done. The individual Subexpressions returned reflect parts
of the match, not subsequent matches. Subsequent matches are found by
calling .Search again.
You seem to be laboring under multiple misconceptions about how RegEx
works, which is going to make forward progress difficult. I'd suggest
throwing out all your assumptions and doing a careful re-reading of the
documentation on them again. Or, perhaps better yet, find a good
introduction to the topic, perhaps in RB Developer or some similar
resource.
Best,
- Joe
