Out of interest, how is it possible to tell that the telephone pole is polystrate without a cross section? Core sections, perhaps? Would be glad if you could clear this up for me.
Just read a little more closely.

Given that both telephone poles were buried by a series of lahars over a period of time, they are entombed not by one layer (stratum) but by a series of series of layers (strata) that were deposited over an extended period of time.

In fact, it appears that we can see these processes happening. It might also be inferred that it could happen since a lahar might incase the lower part of a pole or tree, leaving the upper reaches waiting for the next deposit.
You might also imagine the erosion of an unconsolidated pyroclastic deposit exposing several events and an entombed telephone pole. Remember, YECs tell us that such erosional events happen all the time creating a vast number of grand canyon type features in a very short period.
Perhaps I don't really understand your question. The answer seems kind of obvious...
