That's not necessarily the case. An alpha build is simply a work-in-progress build that isn't robust enough to be considered beta (the latter of which, refers to a build that is feature complete (or nearly feature complete), but still has bugs that need to be ironed out).
A completely playable product can still be branded alpha. Take a look at ResidualVM for example, you could completely play through Grim Fandango with it for over a year without any crashes while it was still in alpha stage (it stayed in alpha simply because it had many glitches and some of the program-specific features didn't work quite right).
