In some setups it might "just work" if you shift like that, but it's probably not giving you optimal shift performance, and it's more trouble than it's worth to be counting those fine clicks.
That's how they worked on my Bridgestone; though, they were stem-mounted Shimano L-412 shifters.
Two or three clicks, and you switch to the next cog.
It won't work well with a 10-speed cassette.
But I only use 4 gears on my everyday ride anyway.
