Growth, increase, landing, establishing of consciousness
I think that what you quoted is the converse of SN 12.64 -- which describes how consciousness doesn't grow or become established, i.e. as a result of not "landing".

I guess an analogy is if you have a seed or seedling which lands somewhere then its roots become involved and it grows -- or, it is doesn't land, then it doesn't.


  Suppose there was a bungalow or a hall with a peaked roof, with windows on the northern, southern, or eastern side. When the sun rises and a ray of light enters through a window, where would it land?” “On the western wall, sir.” “If there was no western wall, where would it land?” “On the ground, sir.” “If there was no ground, where would it land?” “In water, sir.” “If there was no water, where would it land?” “It wouldn’t land, sir.” “In the same way, if there is no desire, relishing, and craving for solid food, consciousness does not become established there and doesn’t grow. …




I think I agree with what you said, i.e. that you attach to what's cognized, make plans based on whats's cognized.

But perhaps it's saying the converse too, i.e. that when attaching (or on attaching) to something then the consciousness lands there and evolves -- e.g. glimpse something, feel attracted, then gaze at it, further resolve details of it and fit those into the idea of what's attractive, etc.

I think that's called "grasping signs" -- I don't know the best example of that, but one is e.g. SN 35.235


  You’d be better off mutilating your eye faculty with a red-hot iron nail, burning, blazing and glowing, than getting caught up in the features by way of the details in sights known by the eye.
  Varaṃ, bhikkhave, tattāya ayosalākāya ādittāya sampajjalitāya sajotibhūtāya cakkhundriyaṃ sampalimaṭṭhaṃ, na tveva cakkhuviññeyyesu rūpesu anubyañjanaso nimittaggāho.
  
  For if you die at a time when your consciousness is still tied to gratification in the features or details, it’s possible you’ll go to one of two destinations:
  Nimittassādagathitaṃ vā, bhikkhave, viññāṇaṃ tiṭṭhamānaṃ tiṭṭheyya, anubyañjanassādagathitaṃ vā tasmiñce samaye kālaṃ kareyya, ṭhānametaṃ vijjati, yaṃ dvinnaṃ gatīnaṃ aññataraṃ gatiṃ gaccheyya
