thermal paste isn't quite as... liquid as liquid metal though.I doubt it's just gonna come out of the heatsink the amount you use is extremely tiny, i've never had thermal paste come from under a heatsink so i doubt this will either. Also pcs are always vertical that point is dumb

to some degree, i suspect the sheet is meant to catch the heat from ram or distribute the heat of the die across that metal casing?To anyone wanting to get better thermals I'd recommend doing direct to die cooling by taking that copper sheet out, fan very rarely turns on after taking it out and putting some decent paste in. Anyone know what the material of the switches heatsink is?
