Wasn't sure if it was 330 or 360 days, and wasn't in a position to look it up when I wrote that post. Thanks for the clarification.

You know, there is a widespread misconception that expats can get around the visa requirements by having their employer "back home" pay them into a bank account back there for work they are doing while out of the country. I've run into any number of people here in France who recommend that approach to American expat trailing spouses. If you're only overseas for a year or two, you can sometimes get away with it, but it's not legal.

Don't know the UK law, but the Americans require that US residents report and pay taxes on all worldwide sources of income, and for the overseas earned income exemption what matters is where you are performing the work and where you are considered resident. Where the employer is located is almost irrelevant.
Cheers,
