My strat has intonation trouble with the b and high e strings. The guitar was set up (not well) by a guitar center technician. All other strings are intonation well besides these two. I have tried moving the saddles up very far, but I would need to move them farther than the screw will allow me in order to get the 12th fret harmonic close to the string pushed down on the 12th fret. Both strings are flat but the b string is very flat.

here's what it looks like

Also, the action is a little lower on the last two strings to compensate for the radius (9.5 I believe). It is a few mm lower which seems significantly different compared to the other strings...

Please help! I'm not sure what to do now.

is the bridge flush with the body?

are the strings brand new?

Just to clarify - your fretted 12th pitch is still flat when the open string is in tune? The way you wrote it almost sounds like you are thinking you should try to adjust the harmonic, using the fretted note as reference, which would be quite backward.

the bridge is against the body and the strings have been used but not worn down. and yes, when the strings are fretted at the 12th, it sounds flat compared to the harmonic at the 12th.

"The strings have been used but not worn down" ---- This isnt very clear. How old are they?

You only adjust the intonation on new strings that have been stretched properly.

if you want to intonate, and the strings are more than a few weeks, swap your strings.

if you want the bridge to be flush you tighten the springs in the back.

the springs in the back were tightened during the set up, and I have been using 9s. I'll try brand new strings and see if that makes a difference.

So a guitar can lose intonation when the strings get worn down? Why doesn't this happen on a piano or an acoustic guitar?

It does happen on piano's and accoustic guitars

Piano tuners adjust the strings at the back (in case of a traditional piano)

On Accoustic guitars you need to adjust the bridge saddle by moving it back and forth. Although this requires you to mod the bridge. ie make the hole for the saddle wider.
