The leads of the crystal should be connected to the mcu pins, and the caps should be connected between each lead of the crystal and ground.
Are you asking why there is a Q1 connected the way we are describing and why there is also a Q2 drawn with dashed lines shown with the leads not connected to the mcu pins, but with each lead connected in series with capacitors to the mcu pins?
I have no idea why Q2, C9, and C10 are there drawn with dashed lines. To me that looks like they should be left unpopulated, but maybe someone else knows why they even appear on the schematic at all.
