The usage of "as well as", some unclear

[belly_ttt]

Problem 1: After reading Micheal Swan's book, the section indicates verbs after as well as, he says:
When we put a verb after as well as, we most often use the -ing form
ex: Smoking is dangerous, as well as making you smell bad (1)

(NOT: as well as it makes you smell bad)

After an infinitive in the main clause, an infinitive without to is possible
Ex: I have to feed the animals, as well as look after the children (2)

So, what I want to ask is, whether in the sentence (1), can we use " As well as makes you smell bad"?
And sentence (2), can we use:" As well as looking after the children"
If positive, what is the difference in the meaning of two sentences above?

Problem 2: After checking on BBC, I found another matter:
"What is interesting in your example, Van Anh, is that if you say: 'I can swim as well as cook well', you are stating that these are two things that you can do, whereas if you say: 'I can swim as well as I can cook', you are stating that you can do both these things to an equal degree of proficiency."

I think, when we use: " I can swim as well as cook well" , we are stating that we can do both these things to an equal degree of proficiency, but when we use" I can swimm as well as I can cook", we just imply there are two things we can do. That means my opinion is opposite to Mr Roger's answer

1 No; the first part of the setence uses a gerund as the subject, so your version doesn't work.
2 I think it's OK, but others may not like it.
3 I can swim as well as cook. = I can do two things (no equal degree of proficiency implied)
I can swim as well as I can cook = the same degree of proficiency

No, Tdol, please notice that Van Anh's version was: "I can swim as well as cook well"

It's a clumsy sentence and it could also imply that the person can swim (unknown degree of proficiency) and cook well, though I doubt that this is the intended meaning.
