Coax Connectivity for MoCA - can't access Coax "endpoint" to check (alien.top)

I preface this by saying I know that nobody can give me a definitive answer with the information provided. I'm curious if anyone dares to offer any vaguely educated guess.

I want to set up MoCA devices in my old (built circa 1900) city apartment. There are two coax cables in the home - one coming in through the window of my living room and the other through the back bedroom window. Once out the window, the cables run all the way down the outside of the building from my fifth floor apartment to... somewhere I can't find or get to.

Is there any way to guess the likelihood that these would be connected (via a splitter?) in a way that would be conducive to MoCA? Would it make any sense for them not to be connected to each other in some way if they are intended to service the same apartment? Is there any way to check without buying additional equipment (with my budget already stretched pretty thin)? I'm willing to gamble a little if they are probably connected, but am wary of investing in two unreturnable MoCA devices if they won't be able to speak to each other.

Who's the provider? Comcast typically will perform this service free-of-charge; that is... grouping and isolating the residence's coax behind a "PoE" MoCA filter.
