HH, As Feisty said,
but, the effect of the entire line is to round UP to the next higher multiple of XMod (if not an exact multiple of XMod already).

StainlessS,
I gave myself dummy of the week award for not realising, especially as I just finished revamping my own cropping and resizing script which also included similar adjustments to achieve a particular mod.

I have modified OP a little, posting here first before sister thread:- https://forum.doom9.org/showthread.php?t=174527
simply because it was the "Headline" post here.

Mods,
Added args
Code:
    Int "src_left", Int "src_top", Int "src_width", Int "src_height",
    \ Bool "Pad_Rec601"
Selectable coords of input clip, [as per Crop()]
and output padding color for YUV Black, either 0 (default or 16 rec601).
Changed padding output to black.

Perhaps some scripters/scriptors/scriptess's could check it out, I'm not 100% certain that I've done it correctly. (thanks).

EDIT: xMod, yMod now default to the source clip natural colorspace alignment requirement rather than 2.
Now requires both RT_Stats and mt_tools v2.0.

EDIT Added check on xMod, yMod
Code:
    Assert(0 < xMod && xMod % DefXmod == 0, RT_String("%sIllegal xMod(%d, DefXMod=%d)",myName,xMod,DefXmod)) 
    Assert(0 < yMod && yMod % DefYmod == 0, RT_String("%sIllegal yMod(%d, DefYMod=%d)",myName,yMod,DefYMod))
EDIT: Added update to sister thread without thread bump.

EDIT: Oops, fixed cockup. Added in BLUE. EDIT: As we are resizing, it will not be Interlaced, will it !

Code:
    DefXmod = RT_ColorSpaceXMod     DefYmod = RT_ColorSpaceYMod(Laced=False)    # Natural ColorSpace alignment for input clip

Also, what Sharpness/Soft settings did you use for SSim? Perhaps using the Soft variant would reduce the mosquito amplification. I believe the ideal downsizer should have the same blurring metrics as the source. With your settings, SSim is just slightly too sharp. Also it would be good to compare Bicubic with suggested B and C settings.
MadVR has an anti-bloating feature that work wonderfully with SSim downscaling. I wonder if it is possible it add it to AvisynthShader. PS. Thanks a lot for your work, literally the only implementation I've seen of SSim for avisynth.
