I think when I was stopped in Houston they checked my travel history and realised that I had only been in transit on those occasions. To cover their mistake they then made up some excuse that I had, "spent more time in the US than in my country of residence during the year".
Careful here.
Point number 1 is that ideal outcome here is not to be 'inteviewed' at all given the nature of your backstory.
If you are sent to secondary the existance of a ticket back to the Uk within the 90 days may help (I doubt that it could harm) but they have no way of knowing whether you intend to use it.
Why do you think that the CPB official "made a mistake"? Theer seems to be no mistake here - the first officer saw circumstances that he felt warranted a second look. That judjment is absolute at that point - there is no such thing as a mistake here. In secondary the further look bore out and you were sent on your merry way.
I'd advise against trying to 'second guess' the system here - your ties to your home country are weak and the country you are spending most of your time in (Mexico) you are doing so outside of official residency rules.
Come on now - and be honest here - putting yourself in a US CPB agent's shoes, would
you let you in?
