Does it matter if TX start or finish is connected to BX start or finish.

I know it matters which round the combined TX+BX ends are connected to the board.

TX finish to BX start and yes it does matter.

The TX is wound the same as the RX. The buck is wound the opposite way then
the outside of the TX should be closer to gnd (same with buck) as this makes
for less noise.

Cheers. That's the way I did my last coil. Kinda intuitive as the BX is an extension of TX. Thought I would double check. Had a quick scan of the tutorials that on bit of information appears to be missing.
