${if_updatenr} requires at least 4 update cycles?

Issue

I was going to implement mail notification with text blinking in conky. I would expect this to work as intended, using 1-second update interval:

${if_updatenr 1}Hello${endif}${if_updatenr 2}${endif}

However, the blink is not correct - text is displayed for 1 sec, and then is missing for ~3 seconds. If, instead, I do this:

${if_updatenr 1}Hello${endif}${if_updatenr 2}${endif}${if_updatenr 3}Hello${endif}${if_updatenr 4}${endif}

then text blinks uniformly in time, as expected.

This happens even if no other things are present in conky's TEXT. I did not find any limitations on if_updatenr in the documentation. So why doesn't it work properly with two-cycle version?

I wasn't able to reproduce this--the below .conkyrc blinks on and off evenly once per second for me:

conky.config = { 
    out_to_wayland = true, 
    alignment = 'middle_middle', 
    own_window_argb_value = 0, 
    own_window = false,
    default_shade_color = 'grey', 
    draw_shades = true, 
    font = 'Mono:size=13', 
    update_interval = 1,
    default_color = '#ffffff',
} 

conky.text = [[ 
${if_updatenr 1}Hello${endif}${if_updatenr 2}${endif}
]]
