The picture they posted with the ERB crew with the Allrounda crew seems very new, but they've already had the beat finished and mixed weeks ago for Wonder vs Wonder.

It's very possible Wonder vs Wonder's battle has an Allrounda beat, but I don't think it's related to them showing up at ERB's studio.
