pandas DateOffset function

Is it normal that the following would return True ?

What would be the idea behind that ?

import pandas as pd

t = pd.Timestamp('2017-01-01 00:00:00')
t + pd.DateOffset(month=1) == t

Use months instead month for add value 1, not replace, thank you @splash58:

print (t + pd.DateOffset(months=1) == t)
False

Details:

print (t + pd.DateOffset(month=1))
2017-01-01 00:00:00

print (t + pd.DateOffset(months=1))
2017-02-01 00:00:00

If check pandas.tseries.offsets.DateOffset.html:

**kwds

    Temporal parameter that add to or replace the offset value.

    Parameters that add to the offset (like Timedelta):

        years
        months
        weeks
        days
        hours
        minutes
        seconds
        microseconds
        nanoseconds

    Parameters that replace the offset value:

        year
        month
        day
        weekday
        hour
        minute
        second
        microsecond
        nanosecond
