Am I eligible for a Visa on Arrival in Thailand after using a tourist visa as a Mexican passport holder?

Hi there, visa on arrival question, bit complicated. Mexican passport. I currently have a METV, which Ive used to be in Thailand for the last 5 months or so (did 2 border bounces to Laos). Im currently stamped in until 22 Oct, although the visa itself finishes on 9 Oct. No previous visa history before this METV That's all fine.

However, i will travel overseas in the región for 10 days, as of 11 Oct, returning on 22 Oct. My flight home (to México) is on 28th Oct. As my METV will be void, i plan to use the free 15 day VOA option (which Mexicans are eligible for) for the 6 days until my flight home. Flying back into BKK Airport.

I realise no one can say for sure, but is anyone aware of any rules stating that someone is not eligible for the VOA after having had a tourist visa? I plan to show the 20k, flights and hotel bookings, obviously.
