I am using Instrumentation-based Code Coverage，and I get report for a function as below:

It can be seen that for each branch its true and false are both executed at least once, so branch coverage of this function should be 100%.

However in index.html the branch coverage is reported as 3/4.

Is the branch coverage wrong? Or how to possibly interpret this value
