The episode acknowledges this at the end, when Spock says Vulcans feel more deeply. What I think we need to remember is that Vulcans have mental capabilities humans don’t. Human Spock literally did not have the same tools available to him that Vulcans do. It’s likely why Spock has more trouble with his emotions than full-blooded Vulcans.
He also points out that human emotions are different. I assumed this to mean the the rhetorical tools he uses to control his Vulcan emotions are ineffective on human emotions despite Vulcan emotions being stronger. It’s like having a vaccine for the flu, but still getting a cold.
That’s a good explanation of it.
