Indeed, both powers can be read either way.  But we have a CS response that actually jibes with common sense and doesn't violate RAW.  Do you really want basic slide powers to get rediculous damage?  There's no save, since the storm pillar is player created and not hindering terrain.  And there are plenty of powers out there that give slides with no hit necessary.

Also worth noting that by RAW forced movement also triggers it.

But only if applied during the monster's own turn via an interrupt or readied action

Storm Pillar is not at all the same. Storm Pillar is specifically per square. Booming Blade is per "away." Whether "away" can be triggered multiple times is highly amibigious, Storm Pillar's wording is not.

I think you are reading extra meaning into the wording.  Let's take a look at both triggers:

Each enemy that moves into a square adjacent to the pillar on its turn takes 1d6 + your Intelligence modifier lightning damage.

vs

if the target is adjacent to you at the start of its next turn and moves away during that turn...

Storm pillar refers to each *enemy* not each square.  Moving into a square is the trigger, but there's nothing to specify that it occurs each time.  The difference in trigger from booming blade isn't signifcant.  Booming blade's trigger is "moves away."  Move has a specific meaning, namely, leaving one square to enter another.  The away part just tells us which direction the move has to be. 

Neither effect specifies how many times it occurs.  And while both powers could arguably be read to trigger multiple times a turn (although that would be pretty silly) there's no distinction that justifies using a different reading for each power. 

"away" is not ambiguous, it means "the distance between the two creatures increased."  Same definition as Push, inverse of Pull and Charge.

Well, I would argue that you would check the trigger each time a potentially triggering event ocurred.  And since squares of movements are explicitly events, each square of movement would be valid, just as they are for all other triggers.  You're then presented with three questions:

1)  Did it start its turn adjacent to you?  Y/N
2)  If Y, did it move?  Y/N
3)  If Y, was it away?  Y/N

If the answer is yes to all three, then the condition specified in Booming Blade is met.  I'm not clear on how there are any other potential interpretations based on its text.
