bidirectional endpoints

Does "bidirectional endpoints" for K22 mean that one endpoint can be used, for example, for both BULK_IN and BULK_OUT transfers at the same time? According to SDK2.0 for K22F examples that is not the case since different endpoints assigned as USB_CDC_VCOM_DIC_BULK_IN_ENDPOINT and USB_CDC_VCOM_DIC_BULK_OUT_ENDPOINT.

 

Just wanted to double check since according to Endpoint Control register (USBx_ENDPTn) description an endpoint can indeed carry out bidirectional transfers.
