In Google style guide I found the following sentence (emphasis is mine):
Some projects require that an
if
must always always have an accompanying brace.
Is this always always
a typo, or some kind of amplification?

Using always twice is not a typo, but is for emphasis, as you suggest.
A similar effect can be used with never.
You must never never eat wild berries.
Edit: The term palilogy refers to the repetition of a word in a sentence.
Here is a previous ELU question on the topic. It is similar to this question, but the first of the two consecutive words is emphasised.
However this question is about the second word being emphasised, perhaps with a comma:
Some projects require that an
if
must always, always have an accompanying brace.
Here is general list of terms for the repetition of words in a sentence.
