Regex validation bug, it inverts values - javascript

Question

I have the following Regex:

const myRegex = new RegExp(/([a-z|\d]){40,78}/gmi)

I have the following data:

var data = ['abcdefghijlmnopqrstuvxzabcdefghijlmnopqrstuvxz01', 'abcdefghijlmnopqrstuvxzabcdefghijlmnopqrstuvxz02']

I do the following:

1st step:

data.map(d => myRegex.test(d) && console.log(d, 'ok'))
//abcdefghijlmnopqrstuvxzabcdefghijlmnopqrstuvxz01 ok

2nd step:

myRegex.test(data[1])
//true

After performing steps 1 and 2, I execute them again, but this second time the values are inverted !!! Can someone explain to me why?
