yes. As I said in a reply (to myself😀) you would be fine for the next extension due in Jan ‘23. Your passport doesn’t run out until Apr ‘24 and there is no requirement to have any form of X months of validity left on a passport if the extension ends prior to the passport expiry.
The following year, if you don’t get a new passport you’d apply for a year extension in Jan ‘24 but it would only be valid until Apr ‘24 when your passport expires.
