Correct. That's why it is a theory, it needs to be proven or disproven with evidence. But I believe it is within the realm of possibilities.
Again, if Azure is referencing pegmatite dips of 10-20°, then the second pegmatite cannot be connected to the AP12 surface expression as this would result in near-vertical dips closer to 70-90°. The shallow dip of the pegmatite affects surface expression. Here are two dikes - both are 10m wide, the brown has a dip angle of 80° and the dark grey has a dip angle of 10°. Both have drastically different outcrop sizes, yet both are still 10m wide.



The surface pegmatite IS AP12, as referenced by the A-AA cross-section.



Below is what I believe it first looked like pre-deformation, followed by what it may look like now.
