How to call it? 'to be getting on'

[Butterfly 55 1]

Hi, 'to be getting on' comes from the phr

Sorry. ' to be getting on' comes from the phrasale verb ' to get on', as like in 'When can we get on with this than.' make further or carry on. Though, 'He seems to be getting on with his home work.'  sounds a bit strange to me - passive voice of the infinitive?

Thanks in advance.

'get on' also has a sense of 'progressing with something'. That's what the idea is here: He seems to be making progress in doing his homework.
