I understand your wonder, but thinking at it this is a very good way to:
look to VST parameters and pattern editor at once
view only the VST instruments you need to automate
easily use pattern effects to change parameters values
if your VST instrument can be automated via MIDI Control CHange messages (almost every VSTi can), the I personally suggest you to use the MidiCCDevice, which will allow you to better organize the automation because this way you can select the VST parameters you see in the device and use only them
