Noun modifiers do have to "touch" the nouns they modify, so an opening modifier would be required to modify the noun after the comma.
A pronoun does not absolutely have to be close to, or "touch" the noun that it refers to. It often does, though, simply because if there are multiple nouns that could be the referent, then placing the noun and pronoun in clear relation to one another avoids the ambiguity.
When you have an opening dependent clause, you pretty much know you're going to have a noun after the comma (because you need to start the independent clause sometime!). So if you have an opening dependent clause and you *don't* put the noun it's referring to after the comma, there's potential ambiguity - is the pronoun supposed to refer to that first noun or something else?
Before she went to work, Amy drank some coffee with Beth.
Who is the opening clause referring to, Amy or Beth? Convention says it should be Amy.
We can also look at the structure of the phrases or clauses in question. When the opening depedent clause uses a subject pronoun, then structurally, the subject after the comma should be the match. This goes with your first example: Because they..., dancers maintain. "they" is a subject pronoun and "dancers is the subject of the main clause. That's a good structural match.
Your second example starts with an "ing" opener, which works a little differently. Now, we have "something originating" but the word "something" isn't actually written there. In fact, no pronoun is written to refer to whatever is "originating." This is more of a pure modifier: it's talking about something but not giving us any clues as to what it's talking about. What's originating? I have no idea. In this case, the noun following the comma MUST be whatever is originating. Is it in this case? Yes - the sounds are originating. So far, so good.
The pronoun "their" is now part of a prepositional phrase (from their foreheads) - it's no longer a subject pronoun; as you note, it's a possessive pronoun. So I don't necessarily expect the subject of the sentence to match with this possessive pronoun. It might... but it doesn't absolutely have to. (And, in this case, it doesn't.)
It still sounds kind of awkward - I probably wouldn't write a sentence in that way myself. :)
