Con los comentoscomentarios de mi pregunta, yo he podido investigar este tema más, y todo lo que he encontrado parece decir lo contrario del podcast.
Un artículo de SpanishDict del pretérito perfecto (Present Perfect) dice esto:
The Spanish present perfect (el pretérito perfecto compuesto o el antepresente) is used to talk about things that started in the past and which continue or repeat in the present. It's also used to talk about things that have happened in the recent past.
Un artículo de ThoughtCo se llama ‘Haber’ and ‘Estar’ Used in Forming Compound Past Tenses dice esto:
In general, the present perfect tense is used to discuss actions that took place in the past but still have relevance to the present or are continuing up to the present.
Curiosamente, este artículo de Real Fast Spanish, que se llama How to Use the Spanish Present Perfect Tense, dice el completo opuesto del podcast que escuché:
To reiterate, any event that started in the past and continues into the present moment requires the use of the present perfect tense.
¡Gracias a todos por su ayuda!
