Do both strikes from Dual Chop receive STAB?

Question

If you were to compare a Haxorus using Dragon Claw (Effective base 120 after STAB) to a Haxorus using Dual Chop, would Dual Chop also have a cumulative base power if 120?

Note: I am aware there is a post like this one from two years ago, but I found the answer ambiguous, unhelpful and was wondering if changes in the X/Y Metagame would affect what I'm asking.

Answer 1

They would both recieve stab and have 120 power after STAB calculation. 6th Gen hasn't changed the boost you get with STAB, so you still get 50%.

>The same-type attack bonus was introduced in Generation I and has remained unchanged since.

Answer 2

Yeah both strikes receive STAB

Nothing has changed with STAB mechanics to my knowledge.
