Peripherals sync with instantaneous operations of 6502

This is more a question than a real issue, albeit that could be an issue.

Hasn't the CPU a few cycles of advance to the peripherals of the NES? The olc6502 performs the whole instruction in the first clock of an instruction:

olcNES/Part #5 - PPU Foregrounds/olc6502.cpp

Lines 288 to 289 in 4dbe2e7

	// Perform operation
	uint8_t additional_cycle2 = (this->*lookup[opcode].operate)();

olcNES/Part #5 - PPU Foregrounds/olc6502.cpp

Lines 318 to 319 in 4dbe2e7

	// Decrement the number of cycles remaining for this instruction
	cycles--;

@OneLoneCoder mentioned this emulator emulates only the behaviour and is not cycle-accurate but doesn't this cause sync issues? In particular, I am thinking of the PPU since it performs operations at every clock cycle.
