Does this adapter help connect a MacBook Pro to a Thunderbolt 2 docking station?

Yes, you can use this adapter to connect a Thunderbolt 2 dock with two displays to a 2018 13" MacBook Pro. You'll need to connect your Thunderbolt 2 cable between the Thunderbolt 2 dock and the Thunderbolt 3 to Thunderbolt 2 adapter.

It sounds like you have two HP monitors connected to a StarTech Thunderbolt 2 dock. They will be limited to 4K 30Hz or 2560x1600 60Hz. One connects via HDMI. The other connects via DisplayPort from the second Thunderbolt 2 port. It should all behave the same when you connect the Thunderbolt 2 dock to a Thunderbolt 3 computer using the Thunderbolt 3 to Thunderbolt 2 adapter.

Some Thunderbolt 2 docks like the OWC Thunderbolt 2 dock can support a display from either the Thunderbolt 2 port or the HDMI port, but not both at the same time unless one display is a Thunderbolt display or is connected to a different Thunderbolt device later in the Thunderbolt device chain (which is basically what a Thunderbolt display is - a Thunderbolt device with a display connected internally to it).

Thunderbolt 3 docks can support two 4K 60Hz displays (twice the bandwidth of Thunderbolt 2).
