Question about 8753ES with Option H39

I've been reading about an 8753ES Option H39 (three test ports) and have some questions about it.

I understand about this option's utility for characterizing three-port devices, but are there any disadvantages to it (i.e., are there applications where a standard two-port 8753ES will outperform an Opt. H39 analyzer)?

For example, it seems there must be at least one more level of switching between the ports and the receivers to make the H39 work, and this added complexity might introduce more losses, crosstalk, etc.

Any insights would be welcome!
