There is nothing to stop me putting all those tells into a macro. Now with one keypress, I can execute that macro. So I could get my character to walk forward, cast a a spell, turn around, cast another spell, all with one keypress. I'm sure Blizzard did not intend this sort of behaviour be allowed.

I'd love to get some clarification from Blizzard on this chat control mechanism.
No, that does NOT work. There is no queueing in the software. I really suggest you try it for yourself before making false assumptions.
