Understanding single-shot alarms from Counter API

[manuargue]

Hello. The doc for the set_channel_alarm function from the Counter API, states:

Set a single shot alarm on a channel. After expiration alarm can be set again, disabling is not needed.

The part that confuses me is "disabling is not needed". As I understand, this API is for single-shot alarms, and some GPT running in continuous mode may not stop generating interrupts if not disabled upon expiration (i.e. the alarm won't be single-shot). Shouldn't we disable the channel in that case?
