Here's an example to make it easy for you.

Say this is the buy queue:

60,000
100,000
25,000

Round numbers, nothing unusual.

Then say someone sells 17,188 shares into that queue.

Now the queue looks like this:

42,812
100,000
25,000

Then let's say the next person sells 60,000.
This 60,000 will show up in two transactions - 1 for 42,812 and another for 17,188.

The the buy queue looks like this:

82,812
25,000

See the pattern?

It only takes one order to start something like this off.
