Joined Meshes - small problem

I started experimenting with joined meshes and ran into a tiny (fixable) problem.

I created two cylinders one centered at -0.5 units (z-axis) and the other at 0.5 units. I then joined the two objects, set a seam at z=0  and applied a modifier to taper the whole thing. See screen image  below.

I then baked the sculpties and exported the whole thing which generates a script. Uploaded sculpty maps to SL, created a prim and put two maps into the contents of that prim. Created a new script and copy/pasted the script saved from Blender into it.

I touched the generator prim and two linked tapered cylinders were created. BUT there was a gap between them! See result - red cylinders on result image below

I looked at the blender created script and found these lines:

"if ( tI == 1 )            {                llSetLinkPrimitiveParams( 2, [ PRIM_TYPE, PRIM_TYPE_SCULPT, "Cylinders.001", PRIM_SCULPT_TYPE_CYLINDER, PRIM_SIZE, < 1.00000, 1.00000, 1.00000 >, PRIM_ROTATION, < 0.00000, 0.00000, 0.00000, 1.00000 >, PRIM_POSITION, < 0.00000, 0.00000, 1.00000 > ] );                addPrim( "Primstar" );            }

 else if (tI > 0 )            {                llSetLinkPrimitiveParams( 2, [ PRIM_TYPE, PRIM_TYPE_SCULPT, "Cylinders", PRIM_SCULPT_TYPE_CYLINDER, PRIM_SIZE, < 1.00000, 1.00000, 1.00000 >, PRIM_ROTATION, < 0.00000, 0.00000, 0.00000, 1.00000 >, PRIM_POSITION, < 0.00000, 0.00000, -0.50000 > ] );                llBreakLink( 1 );            }"

For " tI == 1 " the prim position is being set as < 0.00000, 0.00000, 1.00000 >. Changing that to < 0.00000, 0.00000, 0.50000 > produces the desired result - blue cylinders in result image below.

So my question is - am I screwing up or is there a bug somewhere?
