Sam: I’m working with your logic here.
Yeshivish is Chareidi and Chasidish is Chareidi.
So, yes, Feif’s current MO community and young Syag’s MO community have commonality, both being MO.
A Lakewood yungerman and a Boro Park Chosid have commonality, both being Chareidi.
And the Chareidi yungerman has more in common with the Chareidi Chosid than with the MO Feif. And MO Feif has more in common with the young MO Syag, than he does with the Chareidi yungerman.
