what type of construction is this?

Hi Friends,

What sort of construction is the underlined part below? I understand it is to explain more on "scheme" mentioned in the prior sentence; however, my question is regarding the construction - if we take out "because..." parts then only two words remain in the sentence, and If we keep "because..." parts then why there are commas in place?

Yet in the light of day, the holes in the rescue plan are plain to see. The scheme is confused and unconvincing. Confused, because its financial engineering is too clever by half and vulnerable to unintended consequences. Unconvincing, because too many details are missing and the scheme at its core is not up to the job of safeguarding the euro.

Appreciate your inputs. Thanks

The commas are used to indicate ELLIPSIS: the omission of words whose presence is understood.

The underlined portions are extensions of the preceding sentence:

[The scheme is] confused because its financial engineering...

[The scheme is] unconvincing because too many details...

Two advantages of this construction:

-- emphasis is placed on confused and unconvincing because each word is repeated
-- what would otherwise be a long, single sentence is broken into three separate thoughts, allowing the reader to digest the information bit by bit.

Can someone please elaborate this?
