nope, you see whats being sold. Are the shares not getting bought ? If the company wasn't supporting the bid this would retrace much futher than just a few pennies on each leg up.
You will not always see a pattern when a company is buying back shares. There are lots of ways shares can be bought back at different intervals, different amounts, different prices etc...
The way the float dried up yesterday makes me wonder if they are not buying back shares.
