Seems the answer is that's the way it's going to be now.

3. What must UK nationals who already have a permit for Switzerland (short-stay, residence or cross-border commuter permit) now do?
UK nationals living in Switzerland who obtain a short- or long-stay residence permit before 31 December 2020 and are therefore officially registered in a local commune do not generally need to take any action. The same applies to persons with an EU/EFTA cross-border commuter permit.
However, UK nationals with a valid permit may be informed that they need to exchange their current permit for a different one. This will not affect their existing right to remain, as long as they continue to meet the relevant residence requirements under the AFMP. If they are not informed that they need a different permit, they must simply apply for a new permit before their existing one expires, as usual.
After 31 December 2020, UK nationals will be issued with a biometric residence permit marked (in German, French and Italian) “In accordance with the CH-UK agreement of 25.02.2020”."
