Interesting. ML 9.0 does the same, only JWasm pops the "uses".

This problem is well knowen to me: masm simply cooks sometimes when using SEGMENT/ENDS inside procs. The only solution is to use .data/.code to switch the segments - as long as not using your own defined code segments it should be no problem.
