Reading CPU profile snapshot in Chrome DevTools: is it multiple calls or one?

I’m profiling an application and I’m not sure how should I interpret the call chart. As far as I understand if a bar is split into several ones on the next line, that means that the top function calls underlying functions several times.

I mean, when I see the following in the chart:

| fn1                                                   |
| fn2     | fn2                 | fn2        | fn2      |
| ...                                                   |
| value   | value               | value      | value    |

I read it as fn1 was called only once and value was called four times inside that fn1 call.

The thing is if I insert console.log into that value function, I see it called exactly once. So what does that mean, that I have many columns with value?
