关于情态动词的平行的几个例句的总结及疑问

Monzki

情态动词的平行，来自RON的视频
情态动词在平行结构中可以放在主语前，如果被分开会awkward。
Eg：（注意在一下七个例子中我们讨论的是情态动词而不是行为动词）
I know more Shakespeare than my brother does. 正确
I know more Shakespeare than does my brother. 正确（情态动词在平行结构可放主语前）
I know more Shakespeare than my highly educated brother does. 正确（名词前的形容词/修饰语没有任何影响）
I know more Shakespeare than does my highly educated brother. 正确
I know more Shakespeare than my brother, who has not studied British literature, does. Awkward 注意如果does的这个位置放行为动词，这个句子就是正确的。
I know more Shakespeare than my brother does, who has not studied British literature.错误（不能在名词与名词修饰语间加动词）
I know more Shakespeare than does my brother, who has not studied British literature.正确（如果名词后面有修饰语，应该把情态动词放在名词及修饰语前面）

但是这一个句子我不理解I know more Shakespeare than my brother, who has not studied British literature, does. 为什么Awkward？为什么如果does的这个位置放行为动词，这个句子就是正确的？

请高人指点，谢谢~

个人观点：
因为这个句子还可以这么写：
I know more Shakespeare than DOES my brother, who has not studied British literature.
如果主语有长修饰语隔断谓语，习惯上应该把该修饰语置于句尾以保证主谓连续性。

Manhattan P220 关于TOUCH RULE的特例:
2. A very short predicate falls between, shifting a very long modifier back.

Right: A new CEO has been hired who will transform the company bv decentralizing
authority to various division heads while increasing their accountability
through the use of public scorecards.

The alternative construction is confusing, because the modifier is extremely lengthy:

Awkward: A new CEO who will transform the company by decentralizing authority
to various division heads while increasing their accountability through the
use of public scorecards has been hired.

那么这一条的原因不准确：

I know more Shakespeare than my brother does, who has not studied British literature.错误（不能在名词与名词修饰语间加动词）

名词和修饰语之间可以有动词，见Manhattan例。这里（1）因为有更好的构造（倒装结构）（2）WHO指代不清。

另外：

原句恐怕是
A. I know () Shakespeare MORE than my brother does.
或者
B. I know more ABOUT Shakespeare than my brother does.
否则Shakespeare怎么能用more修饰呢？

I know more Shakespeare than my brother, who has not studied British literature, KNOWS.
这个句子是无法倒装的，i.e.没有比这更好的结构了。
与之相比DOES置于句尾就不如倒装结构漂亮。
