Citing in two connected sentences I read the answers to this, however I'm searching for an elaborated answer on how two (or more) sencentes are oubviously from one source, and hence can be cited with one citation at the end of all sentences:

For example to reduce a really long sentences: The thing varies in dimension A, because of &lt;long explanation with many commas&gt;. Consequently, it is categorised as 1,2 or 3 [Mr. Twit, 2013]. 

Are linking words like consequently, therefore and so on enough to signal that is originates from one source? Can I swap the dot (.) and the citation [Mr. Twit, 2013] to indicate that the citation does not only belong to the last sentence?

Bonus question: If I write a whole paragraph and add one citation at the end, does this imply that the whole paragraph is quoted?

In gerneal I'm trying to reduce he-said-she-said structures, as they are akward and hinder the information flow.
Read what you have written, and check. Altering the order of punctuation and citation might seem a logical way to do it, but many style guides actually impose the respective order of those elements, and not logic.

In the end, I'm afraid you have to choice of either:


accepting ambiguity of your example
using the author's name to make things clear: “Twit et al. demonstrated that […]. As a consequence, it is categorised as X, Y or Z [Mr. Twit, 2013]”
